# How do you find a slope of (-3,4) and (-5,-5)?

Apr 6, 2018

$m = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}}$

#### Explanation:

The formula for a gradient/slope $\left(m\right)$ is:

$m = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}}$

$m = \frac{\left(- 5\right) - \left(4\right)}{\left(- 5\right) - \left(- 3\right)}$
$m = \left(\frac{- 9}{-} 2\right)$
$m = \left(\frac{9}{-} 2\right) = 4.5$
