What is a proportional relationship?

Back

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

Front

How do you determine if a graph represents a proportional relationship?

Back

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

Front

What does it mean if a graph does not go through the origin?

Back

If a graph does not go through the origin, it indicates that the relationship is non-proportional.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point on a graph, written in the form (X,Y).

Front

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

Back

In a proportional relationship, the slope of the line represents the constant ratio between the two quantities.

Front

What is a non-proportional relationship?

Back

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

Front

How can you identify a non-proportional graph?

Back

A non-proportional graph can be identified by its line not passing through the origin or by having a curve.

Front

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

Back

A proportional table has a constant ratio between the values in each row, while a non-proportional table does not.

Front

What does it mean for a table to be proportional?

Back

A table is proportional if the ratios of corresponding values are equal.

Front

How can you tell if a set of ordered pairs is proportional?

Back

You can tell if a set of ordered pairs is proportional by checking if the ratio of Y to X is constant for all pairs.
