# How do you find the slope of (-3, -1), (-1, 5)?

I found: slope$= 3$
/the slope $m$ of the line joining your two points ${P}_{1}$ and ${P}_{2}$ is given as:
$m = \frac{\Delta y}{\Delta x} = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}}$
$m = \frac{5 - \left(- 1\right)}{- 1 - \left(- 3\right)} = \frac{6}{2} = 3$
