The slope $= 10$ $=10$

$(- 4, - 2) = x_{1}, y_{1}$ $(-4,-2) = color(blue)(x_1, y_1)$

$(- 3, 8) = x_{2}, y_{2}$ $(-3,8) = color(blue)(x_2, y_2)$

The slope is calculated using formula:

Slope $= \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ $=color(blue)((y_2 - y_1) / (x_2 - x_1)$

$= \frac{8 - (- 2)}{- 3 - (- 4)}$ $=(8 - (-2)) / (-3 - (-4))$

$= \frac{8 + 2}{- 3 + 4}$ $=(8 +2 ) / (-3 + 4)$

$= \frac{10}{1}$ $=(10 ) / (1)$

The slope $= 10$ $=10$
