Constant of Proportionality Tables Graphs Equations

Front

What is the constant of proportionality?

Back

The constant of proportionality is the ratio between two proportional quantities, often represented as the unit rate.

Front

How can you determine if a table is proportional?

Back

A table is proportional if the unit rate is constant for all pairs of values.

Front

What does it mean if a table is not proportional?

Back

If a table is not proportional, it means that the unit rate varies and does not remain constant.

What does the point (2, 94) represent in a savings context?

Back

After 2 weeks, they save $94.

Front

How do you write an equation for a proportional relationship?

Back

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

Front

What is the unit rate?

Back

The unit rate is the ratio of two measurements in which the second measurement is 1.

Front

What is an example of a proportional relationship?

Back

If 3 apples cost $6, then the cost per apple is a constant $2, making it a proportional relationship.

Front

What does it mean for a graph to pass through the origin?

Back

A graph passes through the origin if the coordinates (0,0) are included, indicating a proportional relationship.
