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!
