Question

Write an equation in slope-intercept form that is perpendicular to the equation y=4x+8 and passes through the point (-12,-1)

Answer 1

y=-1/4x-4

Explanation:

Given slope: 4

Perpendicular slope: -1/4 (change the sign, and flip the slope)

y=mx+b

Plug the order pair into the equation

-1= -1/4(-12)+b

-1=3+b

subtract three on both sides to get b by itself

b=-4

Therefore, y=-1/4x-4
