# How do you find the slope given (-3,8), (-3,-2)?

Jun 3, 2017

The slope is undefined.

#### Explanation:

The slope, or more technically the gradient, can be worked out using the formula $m = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}}$

Substitute values

$m = \frac{- 2 - 8}{- 3 - \left(- 3\right)}$

$m = - \frac{10}{0}$

However, having a 0 in the denominator means that it is undefined.
