Question

If point Q is reflecting across the x = 1 what are the coordinates of its reflection image ?

Q(3,-2)

Answer 1

Q'(- 1, - 2 )

Explanation:

x = 1 is a vertical line passing through all points with an x- coordinate of 1

(3, - 2) is 2 units to the right of x = 1 ( 3 - 1 ), thus

The reflection is 2 units to the left of x = 1 ( 1 - 2 = - 1 )

Q(3, - 2 ) → Q'(- 1, - 2 )
