Question

which transformation would take figure a to figure b? answer a clockwise rotation of 270° about the origin a clockwise rotation of 90° about the origin a reflection over the x - axis a reflection over the y - axis

Explanation:

Step1: Recall reflection rules

Reflection over y - axis changes $(x,y)$ to $(-x,y)$.

Step2: Observe figure

Figure A and Figure B are mirror - images of each other across the y - axis. Points on Figure A have their x - coordinates negated to get corresponding points on Figure B while y - coordinates remain the same.

Answer:

A reflection over the y - axis
