Question

What is the slope of a line that is perpendicular to y=5/4x+50

Answer 1

m=-4/5

Explanation:

A line perpendicular simply has the negative reciprocal of the slope of the line they gave you. This means you flip it, and multiply by -1 conceptually.

Answer 2

-4/5

Explanation:

Because a perpendicular slope is the the opposite of the original slope.
