There are loads of other points but the (0,0) point can be spotted immediately from Pythagoras' Theorem (3,4,5 triangle).

Any points that solve the equation work.

I assume you know (6,8) works since: (63)2+(84)2=32+42=25 (6-3)^2+(8-4)^2 = 3^2+4^2 = 25 .

Well, try the same with (0,0). There are an infinite number of points that will work! Draw a picture. If you have one point, think about symmetry and therefore what must also be one.
To get other points, simply pick a value for x and substitute it into your equation and this will allow you to find the corresponding values of y.
No problem.
