The slope
$m = - \frac{5}{15}$ $m=-(5)/(15)$

The points given are
$(8, - 1) = x_{1}, y_{1}$ $(8,-1) = color(blue)(x_1,y_1$

$(- 7, 4) = x_{2}, y_{2}$ $(-7,4) = color(blue)(x_2,y_2$

The slope

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

$m = \frac{4 - (- 1)}{- 7 - 8}$ $m=(4-(-1))/(-7-8)$

$m = \frac{4 + 1}{- 15}$ $m=(4+1)/(-15)$

$m = \frac{5}{- 15}$ $m=(5)/(-15)$
