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 identify a proportional relationship from a table?

Back

You can identify a proportional relationship by checking if the ratios of corresponding values are the same.

Front

What does the unit rate represent?

Back

The unit rate represents the amount of one quantity per one unit of another quantity.

Front

How do you calculate the unit rate from a given distance and time?

Back

To calculate the unit rate, divide the total distance by the total time.

What is the ratio of y to x if y = 5 and x = 1?

Back

The ratio of y to x is 5:1.

Front

What is the difference between a proportional relationship and a non-proportional relationship?

Back

In a proportional relationship, the ratio is constant, while in a non-proportional relationship, the ratio changes.

Front

How do you determine if a table shows a proportional relationship?

Back

Check if the ratios of y to x are the same for all pairs of values.
