# What is the slope of any line perpendicular to the line passing through (13,-7) and (5,-2)?

$= \frac{8}{5}$

#### Explanation:

Slope of the line passing through two given points
$m = \frac{- 7 + 2}{13 - 5} = - \frac{5}{8}$
So the slope of the perpendicular to this one is
$= - \frac{1}{m} = \frac{8}{5}$
