$m = 4$ $m=4$

The equation to find slope is

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ $m=(y_2-y_1)/(x_2-x_1)$ .

It does not matter which coordinate is used as $1$ $1$ or $2$ $2$ as long as there is consistency.

So let’s plug in the coordinates into the equation:

$m = \frac{- 1 - 15}{- 1 - 3}$ $m=(-1-15)/(-1-3)$

$m = \frac{- 16}{- 4}$ $m=(-16)/-4$

$m = 4$ $m=4$

Hope this helps!
