The slope is the change in Y over the change in X.
Find 2 points on the line that cross X and Y that are easy to tell what numbers they are.
First point( 0,-4)
Second point (8,0)
The change in Y would be 0 - -4 = 0+4 = 4
The change in X would be 8 -0 = 8
The slope is 4 / 8 which reduces to 1/2
The answer is C.
