You can put this solution on YOUR website!
Let the missing coordinates of the endpoint P be (x,y),
\n" ); document.write( "Mid point given :M(a,k) henceforth
\n" ); document.write( "a=(x+f)/2,2a-f
\n" ); document.write( "K=(y+q)/2,2k-q
\n" ); document.write( "The end point P(2a-f,2k-q)
\n" ); document.write( "
\n" );
