You can put this solution on YOUR website!
We have the coordinates
\n" ); document.write( "A (-3,3) and B(1,-8)
\n" ); document.write( "to find midpoint, we need the following formula:
\n" ); document.write( "\"%28X1+%2B+X2%29%2F2\" , \"%28Y1+%2B+Y2%29%2F2\"
\n" ); document.write( "putting in our numbers, we get
\n" ); document.write( "(-3 + 1)/2 , (3 + -8)/2 - -> (-1, -5/2)
\n" ); document.write( "To find length, we need distance formula, which is
\n" ); document.write( "\"d+=+sqrt%28%28x1-x2%29%5E2+%2B+%28y1+-y2%29%5E2%29\"
\n" ); document.write( "again putting your numbers in, we get
\n" ); document.write( "\"d+=+sqrt%28%28-3-1%29%5E2+%2B+%283-%28-8%29%29%5E2%29\"
\n" ); document.write( "\"d+=+sqrt%28%28-4%29%5E2+%2B+%2811%29%5E2%29\"
\n" ); document.write( "\"d+=+sqrt%28137%29\"
\n" ); document.write( "d ~ 11.70 ~ 11.7
\n" ); document.write( "
\n" );
