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 That has been replaced by

**Curve Fits.**

To add a linear regression to a graph:

Click the cog at the upper right of the graph.

Select

*Curve Fit.*Choose

*Linear.*Click

*Done.*

**Note: You must have data on both axes to add a Curve Fit. **

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.
