What is the constant rate of change?

Back

The constant rate of change, also known as the unit rate, is the ratio of the change in one quantity to the change in another quantity. For example, if you earn $41 per month consistently, that is your constant rate of change.

In the ordered pair (5,2), what does the '2' represent?

Back

In the ordered pair (5,2), the '2' represents the y-value, which is the second number in the pair.

Front

What is the constant of proportionality?

Back

The constant of proportionality is a constant ratio or unit rate that describes how one quantity changes in relation to another. For example, if the constant of proportionality is $9, it means for every unit increase in one quantity, the other quantity increases by $9.

Which statement accurately represents the graph?

Back

$500 is earned for every 8 hours worked.

Front

Define unit rate.

Back

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

What does the x-value represent in an ordered pair?

Back

In an ordered pair (x,y), the x-value represents the horizontal position on a graph.

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 quantity is constant.

Front

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

Back

To find the constant of proportionality from a table of values, divide the value of one quantity by the corresponding value of the other quantity for any pair of values.

Front

What is the formula for calculating unit rate?

Back

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

Front

Explain the significance of the slope in a graph.

Back

The slope of a graph represents the rate of change between the two variables. A steeper slope indicates a greater rate of change.
