Question 207993
x=2 is a vertical line (y is not defined and so can have any value)


the perpendicular line must be horizontal and of the form y=?


this means A and B have the same y-coordinate (1)


x=2 is the bisector of AB so the distance from A to x=2 is the same as the distance from x=2 to B
___ 2 - -4 = ? - 2 ___ 6 = 8 - 2 ___ so the x-coordinate of B is 8


point B is (8,1)
