We can write this as
(x - 5)^2 + (y + 3)^2 = r^2
where r = radius
Plugging in the point (2,5) we have
(2-5)^2 + (5+3)^2 = r^2
r^2 = 9 + 64 = 73
so the required equation is
(x - 5)^2 + (y + 3)^2 = 73
That is about right... 2,514 X 2 = 5,028 so he is about 1,000 off. I will leave the rest to you.
Answer: x+5 with a remainder of 3 (can also be said as 3/x-4)
