Front

What is a proportional relationship?

Back

A proportional relationship is a relationship between two quantities where the ratio of one quantity to the other is constant.

Front

How can you tell if a table represents a proportional relationship?

Back

A table represents a proportional relationship if the ratios of the corresponding values are equal.

Front

What does it mean if a graph passes through the origin?

Back

If a graph passes through the origin (0,0), it indicates a proportional relationship between the variables.

Front

What is a unit rate?

Back

A unit rate is a comparison of two different quantities when they are combined together, expressed as a quantity per one unit of another quantity.

Front

How do you find the unit rate from a given scenario?

Back

To find the unit rate, divide the total quantity by the number of units.

Front

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

Back

The y-intercept is the point where the graph crosses the y-axis, indicating the value of the dependent variable when the independent variable is zero.

Front

What does it mean if a graph is non-proportional?

Back

A graph is non-proportional if it does not pass through the origin or if the ratios of the corresponding values are not constant.

Front

What is the difference between proportional and non-proportional relationships?

Back

Proportional relationships have a constant ratio and pass through the origin, while non-proportional relationships do not.

Front

How can you determine if a graph is proportional or non-proportional?

Back

You can determine this by checking if the graph passes through the origin and if the ratios of the values are constant.

Front

What does it mean if a graph intersects the y-axis?

Back

If a graph intersects the y-axis, it shows the value of the dependent variable when the independent variable is zero, but it does not necessarily indicate a proportional relationship.
