The slope $= - 1$

Explanation:

The coordinates are :
$\left(- 3 , 2\right) = \textcolor{b l u e}{{x}_{1} , {y}_{1}}$

$\left(7 , - 8\right) = \textcolor{b l u e}{{x}_{2} , {y}_{2}}$

The slope is calculated using formula:

Slope =color(blue)((y_2 - y_1) / (x_2 - x_1)

= (-8 - 2) / (7 - ((-3) )

$= \frac{- 10}{7 + 3}$

$= \frac{- 10}{10}$

The slope $= - 1$
