Use the first and lay set of x,y values.

Rate of change is change in y/ change in x:

7-10 / 5- -1 = -3/6 = -1/2

The answer is A.-1/2
A.-1/2 is the answer due to the fact that the rate of change is y/x. The rate at which the y values are changing is -1, and the rate at which the d values are changing is +2. Put them together, -1/2. Hope this helps
