Point A (-4,1) is in the standard (x,y) coordinate plane. What must be the coordinates of point B so that the line x=2 is the perpendicular bisector of AB?
\n" ); document.write( "-------------------
\n" ); document.write( "Draw the picture so you can see what you are doing.
\n" ); document.write( "Plot the point: (-4,1)
\n" ); document.write( "Draw the line x=2; it will pass thru (2,1) and (2,1) will be the mid-point
\n" ); document.write( "of AB.
\n" ); document.write( "----
\n" ); document.write( "Let the coordinates of B be (x,y):
\n" ); document.write( "(-4+x)/2 = 2
\n" ); document.write( "-4+x = 4
\n" ); document.write( "x = 8
\n" ); document.write( "--------
\n" ); document.write( "(1+y)/2 = 1
\n" ); document.write( "1+y = 2
\n" ); document.write( "y = 1
\n" ); document.write( "-------
\n" ); document.write( "The coordinate of B are (8,1)
