STEP 13: We are going to calculate the actual slope of the line. To do, we will need the rise (change between y-coordinates) and run (change between x-coordinates)
- Click the LOGIC tab, then and drag out Delta X.
- Change the variable name from delta_x to run.
- Change x2 to netx and x1 to ballx to subtract the two x-coordinates and get the run!

nety = random.randint(-100,100)
# sprite = codesters.Sprite("image", x, y)
net = codesters.Sprite("soccernet", netx, nety)
net.flip_right_left()
#sprite = codesters.Line(x-start, y-start, x-end, y-end, "color")
line = codesters.Line(ballx, bally, netx, nety, "blue")
slopeguess = float(line.ask("What is the slope of this line?"))
rise = nety - bally
