Question

Write an equation for a line perpendicular to y=4x-5 and passing through the point (-12,1)

Answer 1

Answer:

y = -1/4x - 2

Step-by-step explanation:

Since the line has to be perpendicular, that means the new slope multiplied by the original should be -1. The original slope is 4, so the new one would be -1/4. Now our equation is y = -1/4x + z, z being the y intercept. We can find this by substituting the point in and finding the match. 1= -1/4(-12) + z. z has to equal -2, so the answer is y = -1/4x - 2
