Question

Consider the line y = 5x.

What is the slope of a line perpendicular to this line?
What is the slope of a line parallel to this line?

Answer 1

A slope perpendicular would be -1/5x and a slope parallel would be 5x

Explanation:

Perpendicular means about the opposite, or a reciprocal, which is -1/5x. Parallel means the same so it would be 5x.
