Observing the given graph, we can see that the line passes through the points (0,0) and (2,8). To find the slope of a line we will count out the change in x and y.
We can see that as the graph travels from left to right, the rise, or change in y, is 8. Similarly, the run, or change in x, is 2. slope=rise/run ⇔ m=8/2=4 The slope of the given line is 4.
