What is the unit rate in a proportional relationship?

Back

The unit rate is the ratio of the change in the dependent variable to the change in the independent variable, often expressed per one unit of the independent variable.

What does it mean if a graph is linear?

Back

It means that the graph forms a straight line when plotted.

What is the significance of the origin in a proportional graph?

Back

The origin (0,0) indicates that when the independent variable is zero, the dependent variable is also zero.
