Question

What is the slope of a line that is perpendicular to the line represented by the equation x – y = 8?

Answer 1

Answer:

the slope would be equal to -x or -1

Step-by-step explanation:

First rewrite the equation in correct slope intercept form. Subtract x from both sides and then divide both sides by a negative sign.

  x - y = 8

-x            -x

$\frac{-y}{-} =\frac{-x+8}{-}$

y= x +8

A perpendicular slope is the inverse of the original slope. If the original slope is 2 then the perpendicular slope would be -1/2. In this problem the original slope is 1. The inverse of 1 is -1
