Understanding Relationships: Additive vs Multiplicative

Front

What is an additive relationship?

Back

An additive relationship is when a constant value is added to a quantity to find a corresponding value. For example, if you add 3 to each number in a sequence, it shows an additive relationship.

What is a multiplicative relationship?

Back

A multiplicative relationship is when each value in a set is multiplied by a constant factor to find a corresponding value. For example, if you multiply each number by 2, it shows a multiplicative relationship.

What does it mean if both tables represent a multiplicative relationship?

Back

It means that for each x-value in both tables, the corresponding y-value is obtained by multiplying the x-value by a constant factor.

If you have the equation y = 5x, what type of relationship does this represent?

Back

This represents a multiplicative relationship because y is determined by multiplying x by 5.
