Proportional or NonProportional Review

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

What is a non-proportional relationship?

Back

A non-proportional relationship is a relationship where the ratio of one quantity to another is not constant.

Front

How can you identify a proportional relationship from a table?

Back

If the ratios of corresponding values are equal, the relationship is proportional.

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant ratio in a proportional relationship, often represented as k in the equation y = kx.

Front

What does the equation y = kx represent?

Back

This equation represents a proportional relationship where k is the constant of proportionality.

Front

How do you determine if an equation is proportional?

Back

An equation is proportional if it can be written in the form y = kx, where k is a non-zero constant.

Front

What is the rate of change in a proportional relationship?

Back

The rate of change is the constant ratio of change between the dependent and independent variables.

Front

If y = 75x, what type of relationship is this?

Back

This is a proportional relationship because it can be expressed in the form y = kx.

Front

What does a graph of a proportional relationship look like?

Back

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

Front

What is an example of a non-proportional relationship?

Back

An example of a non-proportional relationship is y = 2x + 3, as it does not pass through the origin.
