The Slope: -1/2 and y-intercept: (0,0)
Now, According to the question:
What is slope and y-intercept examples?
In an equation in slope-intercept form (y=mx+b) the slope is m and the y-intercept is b. We can also rewrite certain equations to look more like slope-intercept form. For example, y=x can be rewritten as y=1x+0, so its slope is 1 and its y-intercept is 0.
The given equation is:
y = -1/2x
This equation is in slope intercept form
y =mx + b where m is the slope and b is the y intercept
To find the slope m and y-intercept b.
Hence, Slope: -1/2 and y-intercept: (0,0)

What are the 4 methods for solving quadratic functions?
There are several strategies for resolving systems of linear equations, including:
(1) Graphing Techniques
(2) The Substitution Method
(3) Using a linear combination
(4) The Matrix Approach
(1) Graphing Techniques: Useful if you simply need a broad answer or are certain that the intersection takes place at an integer location. To find where the two lines intersect, just plot them.
(2) The Substitution Approach: To begin, a linear equation for y must be resolved in terms of x. Substitute that expression for y in the other linear equation after that. A formula will be given to you in x. You'll know the intersection's x-coordinate if you can figure this one out. Insert x into either equation to get the equivalent y-coordinate.
(3) Using a linear combination: Add (or subtraction) a multiple of one equation to (or from) the other equation to make the x-terms or y-terms cancel out. Solve for x (or y, depending on which is left) before substituting to get the other coordinate.
(4) The Matrix Approach: This is actually just a streamlined notation of the Linear Combination approach.

How do you solve K problems?
When we say "solve for K" we mean to isolate K by itself on one side of the equal sign. You can do this by "moving" things from one side to the other using mathematical rules.
What does it mean to solve for K?
To isolate K by itself on one side of the equal sign is what we mean when we say "solve for K." Using mathematical principles, you can accomplish this by "moving" objects from one side to the other. The most crucial rule is that anything you do to one side of the equation must also be done to the other.
The K value, also known as the bending limit, of a cyclotron is the ratio between the obtainable energy and the charge-to-mass ratio, where is the particle's kinetic energy, m is the number of atoms, and k is the variational constant. By dividing the y-coordinate by the x-coordinate, we can calculate k when given any position because it is constant (the same for every point).

How long will it take a car to travel 200km if it has an average speed of 55km hr?
It will take 3 hours and 40 minutes for a car to travel 200km at an average speed of 55km/hr.
200km / 55km/hr = 3.63 hrs
3.63 hrs x 60 minutes/hr = 218 minutes
218 minutes - 60 minutes = 158 minutes
158 minutes / 60 minutes = 2.63 hrs
2.63 hrs + 1.37 hrs (3.63 hrs - 2.26 hrs) = 3.40 hrs
To calculate how long it will take a car to travel 200km at an average speed of 55km/hr, you first need to divide the distance (200km) by the speed (55km/hr). This gives you 3.63 hours. To convert this to minutes, you need to multiply this by 60 minutes/hour, which gives you 218 minutes. Subtracting 60 minutes from this gives you 158 minutes. To convert this to hours, you need to divide by 60 minutes/hour which gives you 2.63 hours. Then, you need to add 1.37 hours (3.63 hours - 2.26 hours) to get a total of 3.40 hours. Therefore, it will take 3 hours and 40 minutes for a car to travel 200km at an average speed of 55km/hr.

What is angle?A pair of rays (half-lines) with a shared terminal are combined to form an angle. The latter is referred to as the angle's vertex, and the rays are sometimes referred to as the angle's legs and other times as its arms. An angle is formed when two straight lines or rays meet at a single terminal.The place where two points converge is known as an angle's vertex. The name "angle" comes from the Latin word "angulus," which meaning "corner."When two lines come together at a common point, an angle is created. They are expressed as a number of degrees, denoted by the symbol °. Acute, right, obtuse, and reflex angles are the other three significant types of angles. 360 degrees make up a circle.Additional angles add up to 180.

The points D(3,-5), E(3, 4), and F(-4, 3) form a triangle. Then 26.701 unit is the perimeter of the triangle.
What is perimeter?The length of a two-dimensional shape's perimeter is referred to as its perimeter. The total length of all the sides of the thing is also a definition for it. The perimeter of the form is equal to the algebraic sum of each side's length. For the various geometric forms, there are formulae accessible. The radius of a shape's edge is known as the perimeter. The length of the shape's edge is measured by its perimeter. All of the shape's sides added together provide it. It just has one dimension and uses linear units to represent itself. In contrast, area quantifies how much space a form takes up.
The points D(3,-5), E(3, 4), and F(-4, 3) form a triangle.
DE = [tex]\sqrt{(3-3)^2+ (4 +5)^2}[/tex]

The contractor for a new school put a rectangular garden in the courtyard. The length of this garden is 5 feet longer than its width. If the area is 414 square feet, what is the length of the rectangle?
The length of the rectangular garden is 23 feet.
What is Area?Area of a two dimensional shape is the total region which is bounded by the object's shape.
Given that,
Length of the rectangular garden is 5 feet longer than its width.
Let w be the width of the rectangle.
Then w + 5 is the length of the rectangle.
Area of a rectangle = Length × Width
Area is given as 414 square feet.
(w + 5) w = 414
w² + 5w - 414 = 0
Factorizing,
(w - 18) (w + 23) = 0
w - 18 = 0, then w = 18
w + 23 = 0, then w = -23
w = -23 is not possible for the width.

The (a) and (c) statements are correct out of five statements are (a) and (c) and other statments i.e., (b), (d) and (e) are too generalised statements.
We have a sample of midterm grades for five students are following 69, 62, 79, 87, 73. Average Formula : It is also called the arithmetic mean, which is calculated by dividing the sum of all given observations to the total number of observations.
Average = (a₁+ a₂+ a₃+ ---+ aₙ )/n
where, a₁, a₂,a₃,--,aₙ --> Obersvations
n --> number of observations
So, Average midgrade is written as

a) Average of midgrade for the sample of five students is equals to 74, so it is a correct statement.

Mackenzie owed $100 after -4 weeks. This means that after 4 weeks, the amount she owed was $100 less than it was at the start.
How many weeks when the amount of money Mackenzie owed her friend was $100?We can use the information given in the table to write a linear equation in the form L = m * t + b, where m is the slope and b is the y-intercept.To find the slope (m), we can use the rise-over-run formula by choosing two points from the table: (t1, L1) and (t2, L2). Let's choose (2, 140) and (5, 80):$m = \frac{L2 - L1}{t2 - t1} = \frac{80 - 140}{5 - 2} = -20$Now that we know the slope, we can use one of the points to find the y-intercept (b). Let's use (2, 140):$L = m * t + b$$140 = -20 * 2 + b$$b = 140 + 40 = 180$So the linear equation that models the relationship between t and L is:$L = -20 * t + 180$To find the number of weeks when the amount of money Mackenzie owed was $100, we can set L equal to 100 and solve for t:$L = -20 * t + 180$$100 = -20 * t + 180$$80 = -20 * t$$t = \frac{80}{-20} = -4$So Mackenzie owed $100 after -4 weeks.

The population will reach 700,000 in the year 2044. The equation to calculate this is t = ln(700000/776000)/(-0.015), which gives t = 42.
1. We are given the population of San Francisco in 2002, which is 776,000.
2. We are also given the equation P=776000e^-0.015, which is a model for the population of San Francisco over time.
3. We need to figure out when the population will reach 700,000.
4. To do this, we need to rearrange the equation to solve for t, the number of years since 2002.
5. Rearranging the equation gives us t = ln(700000/776000)/(-0.015).
6. Plugging in our values gives us t = 42.
