You can put this solution on YOUR website!
Midpoint formula:
\n" ); document.write( "(x1 + x2)/2 , (y1 + y2)/2
\n" ); document.write( "..............
\n" ); document.write( "(-5 + x2)/2 = -2
\n" ); document.write( "(-5 + x2) = -2 x 2
\n" ); document.write( "(-5 + x2) = -4
\n" ); document.write( "x2 = -4 + 5
\n" ); document.write( "x2 = 1
\n" ); document.write( "...............
\n" ); document.write( "(4 + y2)/2 = 1
\n" ); document.write( "(4 + y2) = 2 x 1
\n" ); document.write( "(4 + y2) = 2
\n" ); document.write( " y2 = 2 - 4
\n" ); document.write( " y2 = -2
\n" ); document.write( ".................
\n" ); document.write( "Coordinates of other endpoint = (1, -2)
\n" ); document.write( "Hope this helps. :-)
