Answer:

Given the graph:
When x = -2, the value of y is 3
When y = -4, the value of x is -37
When y = 0, the value of x is -17
When y = 2, the value of x is -7
When y = 3, the value of x is -2

Explanation:

To find the values of y = -4, 0, 2, and 3, we need to find the slope of the line:
Given that at x = -2, y = 3 and at x = 3, y = 4:
we can find the slope using these two given points on the graph:
slope = y2 - y1/x2 - x1

4-3/3-(-2) = 1/5
We can then write the equation in slope intercept form to find the value of b.

Substitute a point on the graph for the x and y to find b:
y = 1/5x + b
4 = 1/5(3) + b

4 - 3/5 = b
b = 3.4

y = 1/5x + 3.4
Plug in the values of y to find x
y = -4, x = -37
y = 0, x = -17
y = 2, x = -7
y = 3, x = -2
