Question

How do you find the slope that is perpendicular to the line `y= -1/2x + 4`?

Answer 1

The perpendicular slope of a given line's slope is it's negative reciprocal.

Explanation:

The slope of that line is,

`m= -1/2`

The negative reciprocal is,

`m = 2`

So the slope that is perpendicular to that line is,

`m = 2`
