You can put this solution on YOUR website!
Start with the given distance formula\r
\n" ); document.write( "\n" ); document.write( " $\"d=sqrt%28%28x%5B1%5D-x%5B2%5D%29%5E2%2B%28y%5B1%5D-y%5B2%5D%29%5E2%29\"$ where

is the first point

and

is the second point

\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"d=sqrt%28%28-6-3%29%5E2%2B%284--8%29%5E2%29\"$ Plug in $\"x%5B1%5D=-6\"$ , $\"x%5B2%5D=3\"$ , $\"y%5B1%5D=4\"$ , $\"y%5B2%5D=-8\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"d=sqrt%28%28-9%29%5E2%2B%2812%29%5E2%29\"$ Evaluate $\"-6-3\"$ to get -9. Evaluate $\"4--8\"$ to get 12. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"d=sqrt%2881%2B144%29\"$ Square each value\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"d=sqrt%28225%29\"$ Add\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"d=15\"$ Simplify the square root (note: If you need help with simplifying the square root, check out this solver)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the distance between (-6,4) and (3,-8) is 15 units \n" ); document.write( "

\n" );
