Rate of change

The rate of change is the ratio of change in the y variable to that of the x variable.

From the given table, we can use the following coordinate (1, -2.15) and (2, -2.70)

• $Rate \ of \ change = \frac{y_2-y_1}{x_2-x_1}$

Substitute the coordinate into the formula to have:

$Rate \ of \ change = \frac{-2.70+2.15}{2-1}\\Rate \ of \ change = \frac{-0.55}{1}\\Rate \ of \ change =-0.55$

Hence the change in amount of gasoline is -0.55
