(4, 2)
(2, 4)
(-2, -4)

Answer 1

The coordinates would be (2,4)

Answer 2

Answer: The answer is (2,4)

Hi! here the notation for a point is (x,y), so a reflection over the x axis will turn a point (x,y) in a reflected point (x, -y). This means that you change y for -y, and x stays the same.

Then if we have the point (2,-4), after the reflection in the x axis, we will get (2,-(-4)) = (2,4)
