How do you find the slope given (1,-2), and (3,-8)?

Jul 19, 2016

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

$m = \frac{- 8 - \left(- 2\right)}{3 - 1}$

$m = \frac{- 6}{2}$

$m = - 3$

$\therefore$ The slope between $\left(1 , - 2\right)$ and $\left(3 , - 8\right)$ is $- 3$.

Hopefully this helps!
