Compare to the general equation for a circle centered at ( $\"h\"$ , $\"k\"$ ) with a radius $\"R\"$ :
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( " $\"%28x-h%29%5E2%2B%28y-k%29%5E2=R%5E2\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "( $\"h\"$ , $\"k\"$ )=( $\"8\"$ , $\"-2\"$ )
\n" ); document.write( " $\"R=9\"$ \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
