Question

answer a reflection over the y - axis a reflection over the x - axis a rotation 90° clockwise about the origin a rotation 90° counterclockwise about the origin

Explanation:

Step1: Recall transformation rules

In a coordinate - plane, a reflection over the y - axis changes the sign of the x - coordinate of each point while keeping the y - coordinate the same. For a point (x,y), its image after reflection over the y - axis is (-x,y).

Step2: Analyze the figures

Looking at Figure A and Figure B, we can see that for each corresponding point in the two figures, the x - coordinates have opposite signs and the y - coordinates are the same. For example, if a point in Figure A has coordinates (x,y), the corresponding point in Figure B has coordinates (-x,y). This is the characteristic of a reflection over the y - axis.

Answer:

A reflection over the y - axis
