Select the pair of equations whose graphs are perpendicular A)5x – 8y = 9
12x - 5y = 7

B)y = 2x–7
X + 2y = 3

C)x + 6y = 8
y = 2x - 8

D)2y = -3x + 5
2x + 3y = 4

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16
