When two variables are inversely proportional when one variable gets larger, the other variable gets smaller.

A scatter graph showing an inversely proportional relationship has a curved gradient.

On an inversely proportional scatter graph when one variable increases, the other decreases but the change is not constant.

The line of best fit on an inversely proportional graph will not cross either axis.


This scatter graph shows that x is inversely proportional to y; as the magnitude of x increases the magnitude of y decreases.	This scatter graph of Image Distance against Object Distance of a Lens begins with a steep negative gradient which becomes more shallow until the gradient is almost zero. The relationship is inversely proportional.
