Exercise 1 Page 237

Variables are represented on the axes. How does fuel usage change as car weight changes?

Variables: Car weight and fuel used
Relationship: The heavier the car, the more fuel is used.

Practice makes perfect

The car weight is the independent variable, which is represented on the horizontal axis. The fuel used is the dependent variable, which is represented on the vertical axis.

The variables are directly proportional to each other, which means that as the weight of the car increases, the amount of fuel used increases, too. The heavier the car, the more fuel is used.
