You can put this solution on YOUR website!
You apply the distance formula: $\"d+=+sqrt%28%28x%5B2%5D-x%5B1%5D%29%5E2%2B%28y%5B2%5D-y%5B1%5D%29%5E2%29\"$
\n" ); document.write( "The two given points are:
\n" ); document.write( "(10, 0) and (-10, 0) so...
\n" ); document.write( " $\"x%5B1%5D+=+10\"$ , $\"y%5B1%5D+=+0\"$ and
\n" ); document.write( " $\"x%5B2%5D+=+-10\"$ , $\"y%5B2%5D+=+0\"$
\n" ); document.write( "Making the appropriate substitution:
\n" ); document.write( " $\"d+=+sqrt%28%28-10-10%29%5E2%2B%280-0%29%5E2%29\"$
\n" ); document.write( " $\"d+=+sqrt%28%28-20%29%5E2%29\"$
\n" ); document.write( " $\"d+=+sqrt%28400%29\"$
\n" ); document.write( " $\"d+=+20\"$ \n" ); document.write( "

\n" );
