the equation of the circle:\r
\n" ); document.write( "\n" ); document.write( "\"%28x-h%29%5E2%2B%28y-k%29%5E2=r%5E2\"\r
\n" ); document.write( "\n" ); document.write( "if center (\"-6\", \"-4\"), than \"h=-6\" and \"k=-4\"; so far, we have\r
\n" ); document.write( "\n" ); document.write( "\"%28x-%28-6%29%29%5E2%2B%28y-%28-4%29%29%5E2=r%5E2\"\r
\n" ); document.write( "\n" ); document.write( "\"%28x%2B6%29%5E2%2B%28y%2B4%29%5E2=r%5E2\"...........to find \"r\", use given point (\"-2\", \"-1\")=(\"x\", \"y\")\r
\n" ); document.write( "\n" ); document.write( "\"%28-2%2B6%29%5E2%2B%28-1%2B4%29%5E2=r%5E2\"\r
\n" ); document.write( "\n" ); document.write( "\"4%5E2%2B3%5E2=r%5E2\"
\n" ); document.write( "\"16%2B9=r%5E2\"
\n" ); document.write( "\"25=r%5E2\"\r
\n" ); document.write( "\n" ); document.write( "your equation is:\"+%28x%2B6%29%5E2%2B%28y%2B4%29%5E2=25\"\r
