What is a unit rate?

Back

A unit rate is a comparison of two different quantities where one of the quantities is expressed as a single unit. For example, if you earn 5 points for every 125 pages read, the unit rate is 5 points per 125 pages.

What does a graph representing a unit rate look like?

Back

A graph representing a unit rate typically shows a straight line that starts at the origin (0,0) and has a constant slope. The slope represents the unit rate.

What is the relationship between graphs and unit rates?

Back

Graphs visually represent the relationship between two quantities. The slope of the line in a graph indicates the unit rate.

How can you identify the unit rate from a graph?

Back

You can identify the unit rate from a graph by determining the slope of the line. The slope represents the change in the dependent variable for each unit change in the independent variable.

What does a steeper slope indicate in a graph?

Back

A steeper slope indicates a higher unit rate, meaning that the dependent variable increases more rapidly with respect to the independent variable.

What is the significance of the y-intercept in a graph?

Back

The y-intercept is the point where the line crosses the y-axis. It represents the value of the dependent variable when the independent variable is zero.
