See the entire solution process below:

The slope can be found by using the formula: $m = (color(red)(y_2) - color(blue)(y_1))/(color(red)(x_2) - color(blue)(x_1))$

Where $m$ is the slope and ( $color(blue)(x_1, y_1)$ ) and ( $color(red)(x_2, y_2)$ ) are the two points on the line.

Substituting the values from the points in the problem and calculating gives:

$m = (color(red)(-5) - color(blue)(5))/(color(red)(-8) - color(blue)(-4))$

$m = (color(red)(-5) - color(blue)(5))/(color(red)(-8) + color(blue)(4))$

$m = (-10)/-4 = 5/2$
