Answer
The slope is $m=+2.5$,
the line rises.
Work Step by Step
Slope is defined as $m=\displaystyle \frac{\text{change in y}}{\text{change in x}}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} .$
If m is undefined, the line is vertical.
If m is positive, the line rises ( y increases as we increase x).
If m is zero, the line is horizontal ( y doesn't change as we increase x).
If m is negative, the line falls ( y decreases as we increase x).

Here,
$m=\displaystyle \frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{6-(-4)}{-3-(-7)}=\frac{10}{4}=+2.5$
The slope is $m=+2.5$, (defined, positive)
so the line rises.
