Question

Describe the transformation.

Answer 1

The image in the link shows two similar figures with same y-coordinates, but different x-coordinates.

Further, the x-coordinates of the LHS figure is the product of -1 and the x-coordinates of the RHS figure, and vice-versa.

Hence, the two images are a reflection of each other.

Since, y - coordinates remain same, the figures show reflection across the y-axis
