Which transformation represents a reflection over the x-axis?
a) (x, y) → (−x, y)
b) (x, y) → (x , −y)
c) (x, y) → (y, x)
d). (x, y) → (−y, x)

B)

Step-by-step explanation:

We know that a reflection is a rigid transformation which maps a figure across a line such that the image looks like the mirror image of the pre-image.

It preserves the size and orientation of the figure such that the pre- image will be congruent to the image.

If we transform a figure by a reflection over the x-axis , the its x -coordinates remains same and the polarity of y coordinate changes.

Such that the rule of reflection over the x-axis will be :-

B. (x, y) -> (x, -y)
