Write an equation in slope-intercept form for the
line perpendicular to y = x + 8 that passes
through the point (-7,8).

Since the Line is Perpendicular

m.m'=-1

The line

y=x+8

Comparing with

Y=mx + C

m=1

m.m'=-1

m'=-1/m = -1/1 = -1.

y-y' = m'(x-x')

The point it passes is (-7,8)

y-8= -1(x--7)

y-8=-1(x+7)

y-8 = -x - 7

y + x -1 = 0.

or In Slope intercept Form

Just Make y the subject

y= -x + 1 This is your answer.

Hope this helps!!!

step-by-step explanation:

just plug in each number for x and see which ones work and don't

can you rephrase the question ? it is unclear : -)
