The slope $= - 1$ $= -1$

The coordinates are :
$(- 3, 2) = x_{1}, y_{1}$ $(-3,2) = color(blue)(x_1 , y_1)$

$(7, - 8) = x_{2}, y_{2}$ $(7, - 8) = color(blue)(x_2 , y_2)$

The slope is calculated using formula:

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

$= \frac{- 8 - 2}{7 - ((- 3))}$ $= (-8 - 2) / (7 - ((-3) )$

$= \frac{- 10}{7 + 3}$ $= (-10 ) / (7 + 3 )$

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

The slope $= - 1$ $= -1$
