Answer:
The graph in the attached figure
Step-by-step explanation:
we know that
The equation of the circle into center radius form is equal to

where
(h,k) is the center of the circle
r is the radius of the circle
In this problem we have


so
the center is the point 
the radius is 
therefore
the graph in the attached figure
