Answer:
Before we begin, I am assuming that each square is one unit for this problem. Now, in order to find the slope of this line, we must determine the change in x and the change in y, and write them as y/x. Based on the diagram the change in x is -2 and the change in y is 4, so it's written as -4/2 = 2. So the slope of this line is 2.
