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

Define constant of proportionality.

Back

The constant of proportionality is the constant value (k) that relates two proportional quantities, expressed as y = kx.

What is the relationship between cups of milk and tablespoons of chocolate syrup in a recipe?

Back

The relationship is proportional; as the amount of milk increases, the amount of chocolate syrup increases at a constant rate.

Front

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

Back

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

Front

If the constant of proportionality is 4, what does this mean in a proportional relationship?

Back

It means that for every unit increase in the independent variable, the dependent variable increases by 4 units.
