m=0

Explanation:

Slope is calculated as the change in y over the change is x (you may have heard of this referred to as "rise over run"). So essentially, how fast is the graph increasing or decreasing?

We use a simple formula to find slope, m=(Deltay)/(Deltax), where Deltay is the difference between the two y-values of the endpoints, and Deltax is the difference of the x-values.

In this case, Deltay = 4-4 = 0, and Deltax = 2-(-2) = 4. Therefore, m=0/4=0
