Proportional vs. Non-Proportional (Graphs and Tables Only)

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 between two quantities where the ratio is not 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

How can you identify a non-proportional graph?

Back

A non-proportional graph does not pass through the origin and may curve or be a straight line that does not start at (0,0).

Front

What does the slope of a proportional graph represent?

Back

The slope of a proportional graph represents the constant rate of change between the two variables.

Front

What is direct variation?

Back

Direct variation is a specific type of proportional relationship where one variable is a constant multiple of another.

Front

What is the equation for direct variation?

Back

The equation for direct variation is y = kx, where k is the constant of variation.

Front

What does it mean if a graph has a slope of 0?

Back

If a graph has a slope of 0, it means that the y-value does not change as the x-value changes, indicating a horizontal line.

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.

Front

What is an example of a non-proportional relationship?

Back

An example of a non-proportional relationship is the relationship between the number of hours worked and total pay when there is a base salary plus hourly wage.
