Distance formula in $\"R%5E2\"$ : $\"d=sqrt%28%28x%5B2%5D-x%5B1%5D%29%5E2%2B%28y%5B2%5D-y%5B1%5D%29%5E2%29\"$ \r
\n" ); document.write( "\n" ); document.write( "Choice of which point is first does not matter, but you must be consistent.\r
\n" ); document.write( "\n" ); document.write( "Choose: $\"x%5B2%5D=-6\"$
\n" ); document.write( " $\"x%5B1%5D=10\"$
\n" ); document.write( " $\"y%5B2%5D=y%5B1%5D=0\"$ \r
\n" ); document.write( "\n" ); document.write( "Then,
\n" ); document.write( " $\"d=sqrt%28%28-6-10%29%5E2%2B%280-0%29%5E2%29\"$
\n" ); document.write( "= $\"sqrt%28%28-16%29%5E2%29\"$
\n" ); document.write( "= $\"16\"$ \n" ); document.write( "
