Question

select the rule that maps figure a onto figure b. (1 point) o r_x - axis o r_90 o r_y - axis o r_180

Explanation:

Step1: Recall reflection rules

Reflection over x - axis: $(x,y)\to(x, - y)$. Reflection over y - axis: $(x,y)\to(-x,y)$. Rotation 180° about origin: $(x,y)\to(-x,-y)$. Rotation 90° counter - clockwise about origin: $(x,y)\to(-y,x)$.

Step2: Analyze Figure A and Figure B

Comparing the coordinates of corresponding points in Figure A and Figure B, we can see that for each point $(x,y)$ in Figure A, the corresponding point in Figure B is $(x, - y)$. This is the rule for reflection over the x - axis, denoted as $r_{x - axis}$.

Answer:

$r_{x - axis}$
