Nick walks up 5 stairs in 6 seconds. Edwin walks down 2 stairs per second. Jeff walks up 7 stairs in 6 seconds. Simon walks down 3 stairs per second. If we graph each of these relationships with the number of stairs traveled (y-axis) with respect to time in seconds (x-axis), we get the lines shown in the graph. Identify and drag the name of each person to the line that represents his situation. Nick Edwin Jeff Simon
