    (2) A-B-C

    Goal: Prove that B is on ray(AC).

    I also need help with:

    Goal: Show that there exist lines l and m such that l does not equal m and l and m intersect.

    in first one u need to get 2 of the 3 slopes of ("AB","AC","BC")
    then u will found that they are equal if there are on one line
    slope of line = (Y2 - Y1) / (X2 - X1)
