Front

What is the formula for finding the constant of proportionality?

Back

The formula is k = y/x, where k is the constant of proportionality, y is the dependent variable, and x is the independent variable.

If the constant of proportionality is 2, what does this imply about the relationship between the two quantities?

Back

It implies that for every unit increase in the independent variable, the dependent variable increases by 2 units.

Front

What is an example of a proportional relationship?

Back

An example of a proportional relationship is the relationship between distance and time when traveling at a constant speed.

Front

If a product's price increases from $5 to $10, what is the constant of proportionality?

Back
