You can put this solution on YOUR website!
To find the distance d between P(8,7) and Q(5,4), use:
\n" ); document.write( " $\"d+=+sqrt%28%28x%5B2%5D-x%5B1%5D%29%5E2%2B%28y%5B2%5D-y%5B1%5D%29%5E2%29\"$ substitute: $\"x%5B1%5D+=+8\"$ , $\"y%5B1%5D+=+7\"$ , $\"x%5B2%5D+=+5\"$ , and $\"y%5B2%5D+=+4\"$
\n" ); document.write( " $\"d+=+sqrt%28%285-8%29%5E2%2B%284-7%29%5E2%29\"$
\n" ); document.write( " $\"d+=+sqrt%28%28-3%29%5E3%2B%28-3%29%5E2%29\"$
\n" ); document.write( " $\"d+=+sqrt%289%2B9%29\"$
\n" ); document.write( " $\"d+=+sqrt%2818%29\"$
\n" ); document.write( " $\"d+=+sqrt%289%2A2%29\"$
\n" ); document.write( " $\"highlight%28d+=+3%2Asqrt%282%29%29\"$
\n" ); document.write( "For the midpoint, you will be finding the x- and y-coordinates of the midpoint, so use:
\n" ); document.write( " $\"x%5Bm%5D+=+%28x%5B1%5D%2Bx%5B2%5D%29%2F2\"$ and $\"y%5Bm%5D+=+%28y%5B1%5D%2By%5B2%5D%29%2F2\"$
\n" ); document.write( "Use the same x- and y-coordinates of the two given points P and Q as above.
\n" ); document.write( "You can do this! \n" ); document.write( "

\n" );
