Feature Request: Line of Best Fit Drawer for SAT Math linear scatter plot practice

The linear scatter plot problems for the SAT Math practice questions do not have a feature to draw a line of best fit. I think that this feature should be added since it affects my answers. Without the ability to draw a line of best fit directly onto the graph, I have a hard time solving the problems accurately. Furthermore, on the real SAT the graph would be on paper (I presume), so I would be able to draw a line of best fit directly on it.
