1) Marie and Seth recorded the distance leaves traveled in a rain runoff channel over time intervals of 2, 4, 6, etc. seconds up to 20 seconds. 2) They need to create a scatter plot to graph the data, with time on the x-axis and distance on the y-axis since distance depends on time. 3) They must determine the range of both the x and y-axis scales based on the recorded time and distance data.
