Answer
-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, $m=\frac{10.2-4.2}{1.4-3.4}=\frac{6}{-2}=-3$.
The slope is negative, so the line falls from left to right.
