Answer:
The center is (0,0).
Explanation:
To find the center of a circle, you have to look at the x^2 and the y^2. Because there are no numbers with them in the equation, the center of the circle does not move. If the equation has been like (x-5)^2 + (y-2)^2=16, then the center of the circle would be at (5,2)
