Hi Celia,

I'm not sure what you mean by algebraic term, but when you find the rate of change, you are actually finding the slope.

You typically use the slope formula:

change in y/ change in x.

It's described in more detail on the following web page:

This page will show how to find the slope given two points and give a few examples of rate of change word problems.

I hope this helps,
Karin
