Question

Select the rule that maps Figure A onto Figure B . (1 point) Responses rx=0 r subscript x equals 0 baseline ry=0 r subscript y equals 0 baseline R90° upper R subscript 90 degrees baseline ry−axis

Answer 1

To determine the correct transformation rule that maps Figure A onto Figure B, let's analyze the possible options.

1. **\( r_{x=0} \)**: This reflects Figure A across the y-axis.
2. **\( r_{y=0} \)**: This reflects Figure A across the x-axis.
3. **\( R_{90^\circ} \)**: This rotates Figure A 90 degrees counterclockwise about the origin.
4. **\( r_{y-axis} \)**: This also reflects Figure A across the y-axis.

Based on the descriptions of the transformations:

- If Figure B is a reflection of Figure A across the y-axis, then either option 1 ( \( r_{x=0} \) or \( r_{y-axis} \) ) could be correct.
- If Figure B is a reflection across the x-axis, then option 2 ( \( r_{y=0} \) ) is the correct rule.
- If Figure B is a 90-degree rotation of Figure A, then option 3 ( \( R_{90^\circ} \) ) is the most accurate.

Without a visual reference to Figures A and B, the determination cannot be definitively made. However, if the transformation involves either reflection or rotation, choose the option that best fits the observed change from Figure A to Figure B.

Pay close attention to whether the orientation and positioning of the figures suggests reflection in the x or y direction or rotation.
