Answer
$m=\frac{1-3}{2-(-2)}=\frac{-2}{4}=-0.5$
Work Step by Step
The slope of the line can be determined by the equation:
$m=\frac{y_2-y_1}{x_2-x_1}$, where x and y are the coordinates of the two given points.
Here, we can substitute in the points $(-2,3)$ and $(2,1)$
$m=\frac{1-3}{2-(-2)}=\frac{-2}{4}=-0.5$
The graph is in the picture below.
