What is the constant of proportionality?

Back

The constant of proportionality is the ratio between two proportional quantities, often represented as k in the equation y = kx.

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

Back

To find the constant of proportionality from a table, divide the value of y by the corresponding value of x for any pair of values.

What does it mean if a relationship is proportional?

Back

A relationship is proportional if the ratio between two quantities remains constant.

Front

What is a unit rate?

Back

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

Front

How is the constant of proportionality related to unit price?

Back

The constant of proportionality can be considered the unit price, as it represents the cost per single unit of an item.

Front

What is the equation of a proportional relationship?

Back

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

Front

If the constant of proportionality is 5, what does that mean?

Back

If the constant of proportionality is 5, it means for every 1 unit of x, y increases by 5 units.

What is the unit rate if 10 miles cost $5?

Back

The unit rate is $0.50 per mile.

Front

How do you determine if a relationship is non-proportional?

Back

A relationship is non-proportional if the ratio between the quantities changes or is not constant.
