Question

Write an equation of a line that is perpendicular to the line x-2y=8

Answer 1

Answer:

y=-2x-4

Step-by-step explanation:

First you make the equation in y=mx+b form

x-2y=8

-2y=-x+8

y=1/2x-4

Then find the perpendicular line by finding the opposite reciprocal of the slope.

y=-2x-4

Answer 2

2x+y=8 is the equation perpendicular to x-2y=8.
