ANSWER
[tex](1,-3)[/tex]
EXPLANATION
We want to find the center of the given equation.
The given equation represents the equation of a circle.
The general form of the equation of a circle is given by:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
where (h, k) = center
r = radius
Comparing the given equation to the general equation, we see that the center of the circle is:
[tex](1,-3)[/tex]
That is the answer.
