Back

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

Front

What does it mean if a table is not proportional?

Back

If a table is not proportional, it means that the ratios of the corresponding values are not constant.

Front

What is the unit rate if a table shows 3 apples for 1 tree?

Back

The unit rate is 3 apples per tree.

Front

If a table shows 10 oranges for 2 trees, is it proportional?

Back

Yes, the unit rate is 5 oranges per tree, which is constant.

Front

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

Back

In a proportional relationship, the line passes through the origin (0,0), indicating that when one quantity is zero, the other is also zero.

Front

What does it mean if a graph is proportional?

Back

A graph is proportional if it is a straight line that passes through the origin.

Front

If a table shows 4 trees for 12 apples, what is the unit rate?

Back

The unit rate is 3 apples per tree.

Front

What is an example of a non-proportional relationship?

Back

An example of a non-proportional relationship is a table where the number of apples does not increase consistently with the number of trees.
