Question

What is the rule for the reflection?

ry-axis(x, y) → (–x, y)
ry-axis(x, y) → (–x, y)
rx-axis(x, y) → (x, –y)
ry-axis(x, y) → (x, –y)

Answer 1

According to the given diagram, its a reflection about Y-axis.

Reflection about Y-axis is (X,Y) → (-X , Y)

The reflection about Y-axis the coordinate remains the same only the sign of X-coordinate changes. If the X- coordinate is positive then it becomes negative and if the X-coordinate is negative then it becomes positive.

Rule for the reflection is (X,Y) → (-X , Y)

Answer 2

The Correct answer is B.

Explanation:

This happens because the reflection is across the y-axis and (x,y) -> (-x, y)
