    The first most important is that it's closest to the origin. After that, if there's a tie it goes to minimal x. The important section in the description is this:

    " Find the point closest to the origin that also satisfies the following properties:

    1. x and y are integers.
    2. x is greater than zero.

    If more than one solution exists satisfying 1 and 2, then choose the point in which x is minimal. "

    So for example the point (1,2) and (2,1) are equally close to the origin; if these were both solutions to the equation, (1,2) would be the correct choice. But (1,8) is further away from the origin than (2,3); if these were both solutions to the equation, (2,3) would be the correct choice.

    I hope that helps clarify.

      You are right, I read too fast and missed the first one
