The midpoint of the line segment ST has coordinates (3,6). If S is the point (4,1), find the coordinates of T.
\n" ); document.write( "I'm obviously stuck with this question though I did attempt to do it.
\n" ); document.write( "Here's my working out.
\n" ); document.write( "Let the coordinate of T be (x,y)
\n" ); document.write( "Then by the midpoint formula ((x+3)/2, (y+6)/2)=(4,1)
\n" ); document.write( "Midpoint formula for x.
\n" ); document.write( "(x+4)/2=3
\n" ); document.write( "x+4 = 6
\n" ); document.write( "x = 2
\n" ); document.write( "--------
\n" ); document.write( "(y+1)/2 = 6
\n" ); document.write( "y+1 = 12
\n" ); document.write( "y = 11
\n" ); document.write( "============
\n" ); document.write( "Note: Parentheses make a difference.
