# How do you find the slope perpendicular to y= 1/2x-7?

May 20, 2018

$- 2$

#### Explanation:

$y = \frac{1}{2} x - 7$

okay this equation is already in slope intercept form:

$y = m x + b$ where m = slope and b = y-intercept

The formula for a perpendicular slope is $- \frac{1}{m}$

so your slope is $\frac{1}{2}$ applying the formula:

$- \frac{1}{\frac{1}{2}} = - 2$
