8 0
A. -3(-1) + 7 = 4
3 + 7 = 4
11 = 4 (wrong)

B. 4x - 8 = 12
4(-1) - 8 = 12
-4 - 8 = 12
-12 = 12 (wrong)

C. -2x + 3 = 1
-2(-1) + 3 = 1
2 + 3 = 1
5 = 1 (wrong)

D. 8x + 5 = -3
8(-1) + 5 = -3
-8 + 5 = -3
-3 = -3 (correct!)

So, in conclusion, D is the correct answer.

andre [41]
If a graph is proportional then the line will go through the origin at point (0, 0). If the equation is proportional then it will be in the form of y=kx with no other operations after. The constant of proportionality is another way to say the slope and in your specific equation the slope would be 1/5.
