Column 1 is labeled x with entries 20, 32, 40. Column 2 is labeled y with entries 25, 40, 50. Which statement explains who will raise $100 with the fewest number of laps? Michelle will, because the slope of the line described by the data in her table is the greatest. Andrea will, because the slope of the line described by the data in her table is the greatest.
