Answer
$m=\frac{1}{5}$
Work Step by Step
To find the slope of an line you need to take a look at two points. With these two points you will fill in the formula of the differences quotient: $\frac{y2-y1}{x2-x1}$. The numbers 1&2 indicate the points the number 2 is the one on the right. Number one therefore is the left point.
In this example this would be: $\frac{-1--2}{3--2}=\frac{1}{5}$ since we have the points A(-2/-2) and B(3/-1).
