You can find the slope of the line connecting any two pts on this graph, but to make things easier, I'll use the points (40,20) and (60,80).  Can you explain why this is a good idea here?
                                     80-20
The slope is then m = ----------  =  60/20 = 3 (answer)
                                      60-40
