Question

Which algebraic representation shows the effect that a reflection over the x-axis will have on the coordinates of a figure?

A. ( x,-y )
B. (-x, y )
C. (-x, -y)
D. (-y, x )

Answer 1

The answer is A. ( x, -y)

Answer 2

A, (x, -y)

Explanation:

When something is flipped over the x axis, the y-coordinates become the opposite of what they were. It makes sense if you think about it- if it flips over the line on the x axis, the x-coordinates will stay the same, and the y coordinates will change.
