For this table of data, identify the graph that shows the most likely line of best fit.

Question

fuel (L) distance (km)
0.5 2
1 4.3
1.5 4.7
2 7.2
2.5 9.1
3 8.6
3.5 11.0
4 14.2
4.5 15.1
5 16.2

Answer 1

There are different types of graphs that could be used to display the data (scatter plot, line graph, etc.). However, assuming that a scatter plot is used to show the relationship between fuel (independent variable) and distance (dependent variable), the most likely line of best fit would be a positive linear correlation, indicating that as the amount of fuel increases, the distance travelled also increases.
