Question

Which of the following shows the coordinates of A (6, 12)
after reflection over the y-axis?

Answer 1

(-6,12) if you start in quadrant 1 and move to quadrant 2 it means that your x value is going to be negative meaning you only change the sign

Answer 2

(- 6, 12 )

Explanation:

Under a reflection in the y- axis

a point (x, y ) → (- x, y ) , then

A (6, 12 ) → A' (- 6, 12 )
