m = (y_2 - y_1)/(x_2 - x_1) = -1/2

Explanation:

A slope's gradient (m) is equal to its rise (change in y value), over run (change in x value) or (y_2 - y_1)/(x_2 - x_1).
Substituting our values into this formula and solving, we get:
m = (-2-0)/(1+3)
m = -2/4
m = -1/2
Therefore the gradient of the slope is -1/2 or 0.5.
