Question

Which pair of equations represents perpendicular lines? A.) y=2x+7 and y=x+7 B.) Y=2x+7 and y=-2x-2 C.)y=2x+7 and Y=2x-7 D.) y=2x-7 and y=-1/2-7

Answer 1

Is D. correctly typed ? I don't see a x term.

Answer 2

Yes

Answer 3

Well as typed, there are no correct answers. D. would be correct if the last equation was:
y=-1/2x - 7.

Answer 4

Perpendicular lines the product of their slopes is -1.
