Answer
$-\frac{1}{3}$; falls
Work Step by Step
We are given that the slope $m$ of the line passing through the distinct points $(x_{1},y_{1})$ and $(x_{2},y_{2})$ is defined as:
$m=\frac{rise}{run}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ (where $x_{2}\ne x_{1}$)
Therefore, $m=\frac{-2-1}{6-(-3)}=\frac{-3}{6+3}=\frac{-3}{9}=-\frac{1}{3}$.
The slope is negative, so the line falls from left to right.
