Answer/Step-by-step explanation:
7. The graph is a proportional relationship because the line passes through the point of origin, (0, 0). To find the equation the proportional relationship the graph represents, we need to find the unit rate of red paint (y) to white paint (x). The unit rate will represent the constant of proportionality, k. Then substitute the value of k in [tex] y = kx [/tex].
Unit rate or k = y/x
Using the point, (4, 1),
k = [tex] \frac{1}{4} [/tex]
Substitute k = ¼ in [tex] y = kx [/tex]
✅The equation would be:
[tex] y = \frac{1}{4}x [/tex]
8. The graph Franco made is incorrect.
The equation, [tex] y = -x [/tex], shows a negative constant of proportionality of -1. Therefore, the slope of the line descend downwards, from the left to the right. So, the graph Franco made to represent the equation, [tex] y = -x [/tex] is not correct.
9. a. Proportional relationship can be represented as [tex] y = kx [/tex]. To derive an equation that represents the graph, find k, the constant of proportionality between variable y and x.
Using the point, (2, 24), therefore:
k = y/x = 24/2 = 12.
Substitute k = 12 in [tex] y = kx [/tex]
✅The equation would be:
[tex] y = 12x [/tex]
b. We know an equation is represents a proportional relationship, when it is tales the form, [tex] y = kx [/tex]. Where k is the constant of proportionality. Thus, for if you substitute the pair of values given (x, y) into the equation, you would get the same value of k for any pair of value you substitute in the given set of values.
Also, we know a graph represents a proportional relationship when a straight line passes through the point of origin, (0, 0), and has a constant of proportionality or unit rate all through.

Answer:

Explanation:
A function is a relation (a set of ordered pairs) with the additional property that: no two pairs have the same first element and different second elements.
The definition is often stated as: A relation in which every x value is associated with exactly one y value. "Exactly one means one but two or more:
{(1,2);(2,3);(3,4);(2,5)} includes the points (2,3) and (2,5). Therefore these set of pairs are not a function.

So you have

+2x+4y=4
So you have
-4x=16
So x=-4
And then you can plug x into any one of the equations and solve for y
2(-4)+4y=4
-8+4y=4
Add 8 on both sides to get
4y=12
y=3

write an equivalent system of equations to the following of equations: 2x+2y=-6 and x-4y=2
Answers
Answer:
A system of equivalent equations is:
x + y = -3
2x - 8y = 2
Step-by-step explanation:
Given
2x + 2y = -6
x - 4y = 2
Required
Write a system of equivalent equations
A system of equivalent equations implies that:
When the new set of equation is solved, the solution is equivalent to the original equation.
To do this, we have to carry out the same operation on both sides of the given equation.
Take for instance
2x + 2y = -6
Multiply both sides by ½
½(2x + 2y) = -6 * ½
x + y = -3
x + y = -3 is equivalent to 2x + 2y = -6
Multiply both sides of x - 4y = 2 by 2
2(x - 4y) = 2 * 2
2x - 8y = 4
2x - 8y = 4 is equivalent to x - 4y = 2
Hence, a system of equivalent equations is:
x + y = -3
2x - 8y = 2
Note that there are more equivalent equations.
The results you get depend on the operation performed on the given equation.

NEED HELP !! give the following information about the linear function on the graph shown.
Answers
Answer:
x-intercept = 6
y-intercept = -4
Slope: m = ⅔
f(3) = -2
Step-by-step explanation:
✔️The x-intercept is the value of x when y = 0. It is the point at which the line of the function intercepts the x-axis. Thus,
x-intercept = 6
✔️The y-intercept is -4. At this point, x = 0. The line intercepts the y-axis at y = -4. Thus,
y-intercept = -4
✔️Slope can be calculated using two points, (0, -4) and (6, 0).
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{0 -(-4)}{6 - 0} = \frac{4}{6} = \frac{2}{3} [/tex]
Slope: m = ⅔
✔️f(3) means, what is the value of y when x = 3.
From the graph, when x = 3, y = -2.
Therefore,
f(3) = -2
