determining a rule for a reflection\nwhat is the rule for the reflection?\n$r_{y - axis}(x,y)\to(-x,y)$\n$r_{y - axis}(x,y)\to(x, - y)$\n$r_{x - axis}(x,y)\to(-x,y)$\n$r_{x - axis}(x,y)\to(x, - y)$
Answer
Answer:
D. $r_{x - axis}(x,y)\to(x, - y)$
Explanation:
Step1: Observe the transformation
Points above x - axis go below.
Step2: Recall reflection rules
Reflection over x - axis changes y - coordinate sign.
Step3: Confirm the rule
For any point $(x,y)$, reflection over x - axis gives $(x, - y)$.
