Question

which equation has a graph perpendicular to the graph of 7x = 14y - 8 ?

Answer 1

do you have choices for the question?

Answer 2

A) y = -2x - 7
B) y = - 1/2x + 1
C) y = 1/2x + 1
D) y = 2x + 9

Answer 3

set the above equation in to y=mx+b.. m being the slope, and to find the perpendicular, you just need to find the reciprocal of the slope with the opposite sign
