Use the midpoint formula,
\n" ); document.write( " $\"x%5BM%5D=%28x%5BX%5D%2Bx%5BY%5D%29%2F2\"$
\n" ); document.write( " $\"2%2Ax%5BM%5D=x%5BX%5D%2Bx%5BY%5D\"$
\n" ); document.write( " $\"x%5BY%5D=2%2Ax%5BM%5D-x%5BX%5D\"$
\n" ); document.write( " $\"x%5BY%5D=2%2A13-8\"$
\n" ); document.write( "Similarly,
\n" ); document.write( " $\"y%5BM%5D=%28y%5BX%5D%2By%5BY%5D%29%2F2\"$
\n" ); document.write( " $\"2%2Ay%5BM%5D=y%5BX%5D%2By%5BY%5D\"$
\n" ); document.write( " $\"y%5BY%5D=2%2Ay%5BM%5D-y%5BX%5D\"$
