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 That has been replaced by the following steps: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.
