Click Calculate Slope and enter in the coordinates for each point, and the calculator will tell you the slope! Even if the line is too big to show, it'll work. Press Click to Draw, click on any two points on the screen, and it'll draw a line and find the slope. If you click Random Line, then it'll draw randomly anywhere on screen and find the slope.
Don't use Click to Draw while typing in coordinates as it will change the coordinates. Music is a little loud, but because it is so long, it takes too long to make it quiet in Scratch. Sounds from freesound.org
