When ( h,k ) is the center of the circle,

Comparing this to the given equation:
(1)
(2)
(3)
------------------------------
(1)
(1)
and
(2)
(2)
and

-----------------------------
The center is at ( h, k ) = ( 1, 2 )
------------------------------
The x-intercept is where

and

Those are x-intercepts
-----------------------
The y-intercepts are where

and

Those are y-intercepts
--------------------------
Here's the plot:
