Megan wants to predict how much gas is left in her tank based on the distance she has driven. She filled up her tank and measured the amount of gas in her tank (in liters) after driving certain distances (in kilometers). Her data is summarized in the table below.


Distance (km)	0	100	200	300	400	500
Gas left (L)	50, point, 0	42, point, 2	34, point, 2	26, point, 0	17, point, 6	9, point, 1

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 x-axis.
