Find the Slope of a Perpendicular Line m=-1/3

$m = - \frac{1}{3}$

Step 1

Use the slope-intercept form to find the slope.

The slope-intercept form is $y = m x + b$ , where $m$ is the slope and $b$ is the y-intercept.

$y = m x + b$

Using the slope-intercept form, the slope is Undefined.

$m = Undefined$

Undefined

Step 2

The slope of a perpendicular line to a vertical line is zero.

$0$
