Click the Green Flag in the top right to start. Click anywhere to place points. Press space to see the line of best fit. Press Q to see/hide all the important variables. Press T to see the line's equation (y=mx+b) In "Levels", recreate the line. You can't place dots in the red areas.
It seems to fall apart when you add more points after drawing a line, so just click the green flag again. If it doesn't work as intended, try again. Thanks, Dr. Huang. I could add more levels but I ran out of steam. The music is "No Place I'd Rather Be" pitched down.
