On the horizontal axis we have points marked 1 and 3 in hours. When we subtract 3 - 1 = 2 hour, we get interval of time. On the vertical axis we have points 2 and 1.5, when we subtract 2 - 1.5 = 0.5 liters we get decreasing in liters. Finally when we divide hours and liters we get

For one hour water decrease 0.25 liters.
