Use the distance formula,
\n" ); document.write( " $\"D%5E2=%28x%5B2%5D-x%5B1%5D%29%5E2%2B%28y%5B2%5D-y%5B1%5D%29%5E2\"$
\n" ); document.write( " $\"D%5E2=%282-7%29%5E2%2B%2812-2%29%5E2\"$
\n" ); document.write( " $\"D%5E2=25%2B100\"$
\n" ); document.write( " $\"D%5E2=125\"$
\n" ); document.write( " $\"D=sqrt%28125%29\"$
\n" ); document.write( " $\"D=5sqrt%285%29\"$
\n" ); document.write( " \n" ); document.write( "
