You can put this solution on YOUR website!
easiest way i remember to do it is to draw it on the graph, make your right triagle and use the pathagorean therom to solve for the hypotnuse.
\n" ); document.write( "so the sides in this case for a is 3 between -4 and -7 and b is 8 between 2 and -6.
\n" ); document.write( "a^2+b^2=c^2
\n" ); document.write( "a=3, b=8, find c
\n" ); document.write( " $\"3%5E2%2B8%5E2=c%5E2\"$
\n" ); document.write( " $\"9%2B64=c%5E2\"$
\n" ); document.write( " $\"73=c%5E2\"$ 73 is prime
\n" ); document.write( " $\"sqrt%2873%29=c\"$ this is the distance of the line between the 2 points, approx 8.544 \n" ); document.write( "

\n" );
