Front

What is the rate of change?

Back

The rate of change is a measure of how much a quantity changes in relation to another quantity. It is often represented as a slope in a graph.

Front

What is the unit rate?

Back

The unit rate is a comparison of two different quantities when they are combined together. It is expressed as a ratio of one quantity to one unit of another quantity.

Front

How do you find the constant of proportionality?

Back

The constant of proportionality can be found by calculating the unit rate, which is the ratio of two quantities.

Front

What is the equation for a proportional relationship?

Back

An equation for a proportional relationship can be expressed in the form y = kx, where k is the constant of proportionality.

Front

If 10 ride tickets cost $15, what is the unit rate?

Back

The unit rate is $1.50 per ticket.

Front

What does it mean if one park has a lower unit rate than another?

Back

It means that the tickets at that park are cheaper per ticket compared to the other park.

Front

What is the constant of proportionality in the relationship y = 18.50x?

Back

The constant of proportionality is 18.50.

Front

How can you compare unit rates from different sources?

Back

You can compare unit rates by calculating the cost per unit (e.g., per ticket) for each source and determining which is lower.

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

If the unit rate is 7, what does that signify?

Back

It signifies that for every unit of the second quantity, the first quantity increases by 7.
