This program finds the best-fit line, or regression line, of a scatter plot. Some lines may be a little off.
Change the X and Y sliders to move the orange dot.
Press the + or - symbols to plot or remove a point at that location.
Press Go! to draw the best-fit line.
Click the green flag to reset the graph.
This project uses Kitty's Graphing Equations.

Nice!
Thanks. I've added that, although if you don't plot any points a ? shows up.
It would also be nice if the project reported back the slope and Y intercept...
Awesome! Nice interface too!
