Front

What is the rate of change?

Back

The rate of change is a measure of how much a quantity changes in relation to another quantity. It is often represented as a ratio or a slope on a graph.

How do you calculate the rate of change from a graph?

Back

To calculate the rate of change from a graph, find the change in the vertical axis (y-axis) and divide it by the change in the horizontal axis (x-axis). This is often referred to as 'rise over run'.

What does a steeper slope on a graph indicate about the rate of change?

Back

A steeper slope indicates a greater rate of change. This means that for each unit change in the x-axis, there is a larger change in the y-axis.

What does a flat line on a graph represent in terms of rate of change?

Back

A flat line indicates a rate of change of zero, meaning that the quantity on the y-axis does not change as the quantity on the x-axis changes.
