Unit Rate/ Tables and Graphs

Front

What is a unit rate?

Back

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

Front

How do you determine if a relationship is proportional?

Back

A relationship is proportional if the ratio between the two quantities remains constant. This can be determined by checking if the unit rate is the same for all pairs of values.

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

If a table shows values of x and y, how can you tell if they are proportional?

Back

You can tell if they are proportional by checking if the ratios of y to x are the same for all pairs of values.

Front

Calculate the unit rate: 60 miles in 2 hours.

Back

30 miles per hour.

Front

What does it mean if a table is not proportional?

Back

If a table is not proportional, it means that the ratios of the quantities do not remain constant.

Front

Find the unit rate: $4.50 for 6 bottles of water.

Back

$0.75 per bottle.

Front

What is the formula to find the unit rate?

Back

Unit Rate = Total Quantity / Number of Units.

Front

If 10 apples cost $5, what is the unit rate?

Back

$0.50 per apple.

Front

What is a proportional relationship?

Back

A proportional relationship is one where two quantities increase or decrease at the same rate, maintaining a constant ratio.
