      If I can remember!


      (1, 2); m = 4/5


      remember: 1 is x1 and 2 is y1


      formula:


      y - y1 = m(x - x1) 


      y - 2 = 4/5(x - 1)


      y - 2 = 4/5x - 4/5


         +2             + 2


      -------------------------


         y     =   4/5x  - 6/5


      -4/5x      -4/5x


      -----------------------------


      -4/5x + y = - 6/5
