What is an additive relationship?

Back

An additive relationship is when a quantity increases or decreases by a constant amount. For example, in the equation y = x + 3, the value of y increases by 3 for every increase of 1 in x.

What is a multiplicative relationship?

Back

A multiplicative relationship is when a quantity increases or decreases by a constant factor. For example, in the equation y = 2x, the value of y doubles for every increase of 1 in x.

How can you identify an additive graph?

Back

An additive graph typically shows a straight line with a constant slope, indicating a consistent increase or decrease. The equation will be in the form y = mx + b.

How can you identify a multiplicative graph?

Back

A multiplicative graph usually curves upwards or downwards, indicating exponential growth or decay. The equation will often be in the form y = kx, where k is a constant.

What does the slope represent in a multiplicative relationship?

Back

In a multiplicative relationship, the slope is not constant; instead, it represents the factor by which y changes for each unit increase in x.

How do you convert an additive equation to a multiplicative form?

Back

You cannot directly convert an additive equation to a multiplicative form, as they represent different types of relationships.
