#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#.
