Question 975619
<pre>

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.

{{{drawing(400,400,-5,5,-5,5,graph(400,400,-5,5,-5,5),

circle(-2,1,0.09),circle(-2,1,0.07),circle(-2,1,0.05),circle(-2,1,0.03),circle(-2,1,0.01),
locate(-2,1,"(-2,1)"),
circle(-2,1,1)  )}}}

{{{(x-h)^2+(y-k)^2=r^2}}}

{{{(x+2)^2+(y-1)^2=1^2}}}

{{{(x+2)^2+(y-1)^2=1}}}
