Question

Write an equation of the line, in the requested forms, that passes through the given point and is perpendicular to the given line. (-8,5) y=4x-4

Answer 1

y = (-1/4)x + 3

Explanation:

to find the perpendicular slope you just find the reciprocal of 4 which is (-1/4)

then find the y-intercept making the line go through (-8, 5) so you do:

y = (-1/4)x + b

5 = (-1/4)(-8) + b

5 = 2 + b

-2 -2

3 = b
