Answers
Given : A Car Was Driven 6 Times To Measure The Distance And The Amount Of Fuel Used.
To Find : plot the data ( scatter plot)
Is there a linear relationship between distance and the amount of fuel used?
Solution:
Distance (km) Amount of fuel used (L)
20 2.14
25 2.75
30 2.65
35 3
28 2.8
40 2.479
relationship is not linear as R² value is 0.165
R² value should be closer to 1
Quadratic relation represent it better as R² value is 0.8 for that
