Proportional vs. Non-Proportional (Easier) - Math BE

Front

What is a proportional relationship?

Back

A proportional relationship is one in which two quantities maintain a constant ratio. This means that as one quantity increases or decreases, the other does so in a consistent manner.

Front

What is a non-proportional relationship?

Back

A non-proportional relationship is one in which the ratio between two quantities is not constant. This means that the relationship does not maintain a consistent rate of change.

Front

How can you identify a proportional relationship in a graph?

Back

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

Front

How can you identify a non-proportional relationship in a graph?

Back

A graph represents a non-proportional relationship if it is not a straight line or if it does not pass through the origin.

Front

What does it mean if a table shows proportional values?

Back

If a table shows proportional values, the ratio of the values in one column to the values in another column remains constant.

Front

What does it mean if a table shows non-proportional values?

Back

If a table shows non-proportional values, the ratio of the values in one column to the values in another column varies.

Give an example of a proportional relationship in real life.

Back

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

Front

Give an example of a non-proportional relationship in real life.

Back

An example of a non-proportional relationship is the relationship between the number of hours worked and the total pay if there is a fixed salary plus overtime.

Front

What is the equation of a proportional relationship?

Back

The equation of a proportional relationship can be expressed as y = kx, where k is the constant of proportionality.

Front

What is the equation of a non-proportional relationship?

Back

The equation of a non-proportional relationship may include a constant term, such as y = mx + b, where b is not equal to zero.
