But I don't really get how. I don't need to know the answer just how to figure it out! Please and thank you. Last edited by HenryW; Feb 8th 2011 at 01:39 PM.

Have you covered linear regression yet? You'll find the needed formulas around the middle of the page. If you've got access to MS Excel, there is a package in there that will do the work for you. If you haven't covered linear regression, then I'd graph the data, sketch in a best fit line, and calculate the slope of that.
