formula: mid point( x,y) =((x1+x2)/2,(y1+y2)/2)
\n" ); document.write( " midpoint( x,y)=(5,-11)
\n" ); document.write( " one point(x1,y1)= (3,5)
\n" ); document.write( " (5,-11)= ((3+x2)/2,(5+y2)/2)
\n" ); document.write( " $\"+5+=+%283%2Bx2%29%2F2\"$ $\"+-11+=+%285%2By2%29%2F2\"$
\n" ); document.write( " 5*2 = 3+x2 -11*2 =5+y2
\n" ); document.write( " 10=3+x2 -22=5+y2
\n" ); document.write( " 10-3=x2 -22-5=y2
\n" ); document.write( " 7=x2 -27=y2
\n" ); document.write( " hence other end point(x2,y2)=(7,-27) \n" ); document.write( "

\n" );
