Front

What is the constant of proportionality?

Back

The constant of proportionality is the ratio between two proportional quantities, indicating how one quantity changes in relation to another.

Front

What does a unit rate represent?

Back

A unit rate is a comparison of two different quantities when they are combined together. It shows how much of one quantity corresponds to one unit of another quantity.

Front

How can you identify a proportional relationship from a graph?

Back

A proportional relationship can be identified from a graph if the line passes through the origin (0,0) and is straight.

Front

What is the formula for finding the constant of proportionality?

Back

The constant of proportionality can be found using the formula k = y/x, where k is the constant, y is the dependent variable, and x is the independent variable.

Front

If 100 is earned for each hour worked, what is the unit rate?

Back

The unit rate is $100 per hour.

Front

What does it mean if a relationship is non-proportional?

Back

A non-proportional relationship means that the ratio between the two quantities is not constant; as one quantity changes, the other does not change at a constant rate.

Front

How do you find the constant rate of change from a table?

Back

To find the constant rate of change from a table, divide the change in the dependent variable by the change in the independent variable.

Front

What is an example of a proportional relationship?

Back

An example of a proportional relationship is if a car travels 60 miles in 1 hour, it will travel 120 miles in 2 hours, maintaining a constant speed.

Front

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

Back

The slope of the line in a graph representing a proportional relationship indicates the constant of proportionality.

Front

If a graph shows that $500 is earned for every 8 hours worked, what is the unit rate?

Back

The unit rate is $62.50 per hour.
