As you can see in graph A the more gallons of gas used the more you pay.

Independent Variable: Gallons of gas
Dependent Variable: Dollars

Graph B shows that as you age your growth increases.

Independent Variable: Age
Dependent Variable: Height (in.)

Graph C shows level of ozone concentration decreasing as the years increase.

Independent Variable: Years
Dependent Variable: Level of Ozone Concentration

Graph D shows a step function data which seems to show the number of students and classrooms.
For example, you would have only 1 classroom with 30 students and as the number of students increase the number of classrooms increase.
