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

Y = 2x - 7
Y = -1/2x + 4
Y = 1/2x + 1
Y = 2x + 9
B?

Answered by Reiny
7x - 14y = -8 has a slope of 1/2

so the perpendicular must have a slope of -2

none of your choices have a slope of -2
I suspect a typo in your answer choices.
