  1. We worked this problem out and only found 4 possible answers. Do you think there are more than that?

    Our other answers were (1,4), (9,2) and (1,3), (8,2).

    Thanks!

    • there are many more, if you think in terms of slope, any that create perpendicular lines will work; all the points to the left or right two and up one will be the same as going left or right one, then up two. etc
