Yes. I assume you mean (x2 + y2) / (a2 + b2) = 1. Set all the variables to the same value - for example, all equal to one - and you have a valid solution.
Yes, and also a negative integer divided by a negative integer is equal to a positive number (but not necessarily an integer).
None of the graphs that I can see!
That means there is an integer which, when squared, is exactly equal to 64.
