x%5E2%2By%5E2-2x%2B6y%2B10=0
Complete the square in x and y.
x%5E2-2x%2By%5E2%2B6y%2B10=0
%28x%5E2-2x%2B1%29%2B%28y%5E2%2B6y%2B9%29%2B10=1%2B9
%28x-1%29%5E2%2B%28y%2B3%29%5E2%2B10=10
%28x-1%29%5E2%2B%28y%2B3%29%5E2=0
It's a circle centered at (1,-3) with a radius of zero.
In other words, it is the point (1,-3).
