Front

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

Back

After 2 weeks, they save $94.

Front

What is a proportional relationship?

Back

A relationship where the ratio between two quantities remains constant.

Front

How can you determine if a table represents a proportional relationship?

Back

Check if the unit rate (slope) is constant for all pairs of values.

Front

What is the unit rate in a proportional relationship?

Back

The constant ratio of the dependent variable to the independent variable.

Front

What does a non-proportional graph look like?

Back

A graph that does not pass through the origin or has a changing slope.

Front

What is the formula for a proportional relationship?

Back

y = kx, where k is the constant of proportionality.

Front

How do you identify the constant of proportionality in a table?

Back

Divide the dependent variable by the independent variable for any pair of values.

Front

What is the significance of the origin (0,0) in proportional relationships?

Back

It indicates that when the independent variable is zero, the dependent variable is also zero.

Front

What is an example of a proportional relationship in real life?

Back

The relationship between distance and time at a constant speed.

Front

What does it mean if a table is not proportional?

Back

It means the ratios of the dependent variable to the independent variable are not constant.
