Equations don't have centers.
====================
I knew what you meant, too.
But I think it's important that you be able to say what you mean, and not depend on someone else to figure it out.

He's a smarty-pants.  I knew what you meant. You meant
"What is the equation of the circle which has center (-2,1)
that is tangent to the x-axis.



%28x-h%29%5E2%2B%28y-k%29%5E2=r%5E2

%28x%2B2%29%5E2%2B%28y-1%29%5E2=1%5E2

%28x%2B2%29%5E2%2B%28y-1%29%5E2=1
