Start with:
\n" ); document.write( " $\"d+=+sqrt%28%28x%5B2%5D-x%5B1%5D%29%5E2%2B%28y%5B2%5D-y%5B1%5D%29%5E2%29\"$ where: d = distance, and the x- and y-coordinates of the two given points 1 and 2 are the ( $\"x%5B1%5D\"$ , $\"y%5B1%5D\"$ ) and ( $\"x%5B2%5D\"$ , $\"y%5B2%5D\"$ ) respectively.
\n" ); document.write( "Make the appropriate substitutions.
\n" ); document.write( " $\"d+=+sqrt%28%2812-8%29%5E2%2B%2811-8%29%5E2%29\"$
\n" ); document.write( " $\"d+=+sqrt%284%5E2%2B3%5E2%29\"$
\n" ); document.write( " $\"d+=+sqrt%2816%2B9%29\"$
\n" ); document.write( " $\"d+=+sqrt%2825%29\"$
\n" ); document.write( " $\"highlight%28d+=+5%29\"$ \n" ); document.write( "

\n" );
