Proportional Tables and Graphs

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 does the constant of proportionality represent?

Back

The constant of proportionality represents the unit rate in a proportional relationship, indicating how much one quantity changes in relation to another.

Front

What is the unit rate?

Back

The unit rate is the ratio of two measurements in which the second quantity is one unit.

Front

What does a proportional graph look like?

Back

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

Front

What does a non-proportional graph look like?

Back

A non-proportional graph does not pass through the origin and may be curved or straight but does not maintain a constant ratio.

Front

How can you determine if a table of values is proportional?

Back

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

Front

What is the y-axis?

Back

The y-axis is the vertical axis on a graph, representing the dependent variable.

Front

What is the x-axis?

Back

The x-axis is the horizontal axis on a graph, representing the independent variable.

Front

If a graph is proportional, what can be said about the coordinates of points on the line?

Back

If a graph is proportional, the coordinates of points on the line will maintain a constant ratio.

Front

What is 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.
