$- 4$ $-4$

Explanation:

Slope of $(7, - 4), (4, 8)$ $(7,-4),(4,8)$
$x_{1} = 7$ $x_1=7$
$y_{1} = - 4$ $y_1=-4$
$x_{2} = 4$ $x_2=4$
$y_{2} = 8$ $y_2=8$
Slope $= \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ $=(y_2-y_1)/(x_2-x_1)$
$= \frac{8 - (- 4)}{4 - 7}$ $=(8-(-4))/(4-7)$
$= \frac{12}{- 3}$ $=12/-3$
$- 4$ $-4$
