Question

What is the slope of a line that is perpendicular to a slope of -4?

Answer 1

The perpendicular slope `m=1/4`

Explanation:

The perpendicular slope to any given line is the inverse reciprocal of the slope.

Given the original slope of `m=-4` or `m=-4/1`

We can take the inverse and the reciprocal which makes the perpendicular slope `m=1/4`
