Question

Triangle XYZ is shown on the coordinate plane below:

If triangle XYZ is reflected across the line y = 1 to create triangle X'Y'Z', what is the ordered pair of X'?

(−4, 5)
(−2, 5)
(4, −3)
(4, −5)

Answer 1

I believe the answer should be ( 4, -3 )

Answer 2

The answer would be (4,-3) since you know that the point X is 4 units above the line y=1 therefore if reflected across y=1 it would go 4 units down. The x-value would not change due to a reflection over a horizontal line.
