Proportional/Not Proportional Graphs and Tables

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 identify a proportional graph?

Back

A proportional graph is a straight line that passes through the origin (0,0).

Front

What does it mean if a table is proportional?

Back

If a table is proportional, the ratios of the values in the table are constant.

Front

What is a non-proportional relationship?

Back

A non-proportional relationship is when the ratio between two quantities is not constant.

Front

How can you tell if a graph is non-proportional?

Back

A non-proportional graph does not pass through the origin and is not a straight line.

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant ratio between two proportional quantities.

Front

Give an example of a proportional relationship in real life.

Back

An example is the relationship between distance and time when traveling at a constant speed.

Front

What does a slope of a proportional graph represent?

Back

The slope of a proportional graph represents the constant of proportionality.

Front

How do you determine if a table is proportional?

Back

To determine if a table is proportional, check if the ratios of corresponding values are equal.

Front

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

Back

Proportional tables have constant ratios, while non-proportional tables do not.
