In the previous version of the graphing tool there was a button for linear regression. That has been replaced by the following steps:

  • click the cog at the upper right of the graph

  • select Curve Fit

  • choose Linear

  • click Done

You can click on data points on the graph to include/exclude them from the curve fit calculations.

As a student, your data always saves as you go so you can return to your work later to continue or revise.
