Lynn wants to predict how much fuel her car will use based on its speed. She drove her car 100 km at each of the speeds below, and she measured how much fuel was used at each speed. Her data is summarized in the table below. Speed (km/hour) 20 40 60 80 100 120 Fuel used (liters) 13.0 8.0 5.9 7.0 8.3 9.9 All of the scatter plots below display the data correctly, but which one of them displays the data best? By convention, a good scatter plot uses a reasonable scale on both axes and puts the explanatory variable on the r- axis.​
