Question

Point G' has coordinates (-5, 2). If it was reflected across the y-axis, what were the coordinates of its pre-image?

(-5, -2)
(5, 2)
(2, -5)
(5, -2)

Answer 1

Answer: Second answer, (5,2)

Explanation:

To reflect across the y axis, it would be: (x,y) -> (-x,y)

So, (-5,2) reflected across the y axis would be (5,2)
