Constant of Proportionality Review

Front

What is the constant of proportionality?

Back

The constant of proportionality is the ratio between two proportional quantities, often represented as k in the equation y = kx.

How do you find the constant of proportionality from a table of values?

Back

To find the constant of proportionality, divide the y-value by the corresponding x-value for any pair of values in the table.

Front

What does it mean when two quantities are proportional?

Back

Two quantities are proportional if they maintain a constant ratio or relationship to each other.

If y = 3x, what is the constant of proportionality?

Back

The constant of proportionality is 3.

Front

What is a unit rate?

Back

A unit rate is a comparison of two different quantities when they are combined together, expressed as a quantity per one unit of another quantity.

Front

How do you calculate the unit price?

Back

To calculate the unit price, divide the total price by the number of units.

If a car travels 150 miles in 3 hours, what is the constant of proportionality (speed)?

Back

The constant of proportionality (speed) is 50 miles per hour.

Front

What is the formula for finding the unit rate?

Back

The formula for finding the unit rate is: Unit Rate = Total Quantity / Number of Units.
