Question 175771: 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 line AB?

You can put this solution on YOUR website! 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 line AB?
----------------
Draw the picture.
The line x = 2 passes thru the point (2,1)
(2,1) is the midpoint of AB
A is 6 units to the left of (2,1), so B must
be 6 units to the right of (2,1)
--------------------
B is (8,1)
=================
