$- \frac{3}{4}$ $-3/4$

The slope formula: $\frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ $(y_2-y_1)/(x_2-x_1)$

$(1, 5) \to (x_{1}, y_{1})$ $(1,5)rarr(x_1,y_1)$
$(- 3, 8) \to (x_{2}, y_{2})$ $(-3,8)rarr(x_2,y_2)$

$slope$ $"slope"$ $= \frac{8 - 5}{- 3 - 1} = \frac{3}{- 4} = - \frac{3}{4}$ $=(8-5)/(-3-1)=3/(-4)=-3/4$
