Answer:
Step-by-step explanation:
Look at where -2 is on the x-axis (the left side of the horizontal line), and go another half a box in, that is -2.5. But then go down one box from there, and plot the point. that is (-2.5,-1).
Next go half a box to the right and two boxes up, and plot your point there. that is (.5,2).
The equation is y = -2x + 120
Since the numbers are going down there is a negative slope.
Substitute 40 in and you will get 40 as your answer.
