• If the x-value of a solution is positive, then
  the corresponding y-value is negative.
• If the x-value of a solution is negative, then
  the corresponding y-value is positive.
• There is no solution for which both the
  x-value and the y-value are integers.
• There is only one solution for which both
  the x-value and the y-value are integers.
