Question

On a coordinate plane, 2 quadrilaterals are shown. The first figure has points A (negative 2, 1), B (negative 4, 1), C (negative 4, 5), and D (negative 2, 4). Figure 2 has points A prime (2, 1), B prime (4, 1), C prime (4, 5), and D prime (2, 4).
What is the rule for the reflection?

rx-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

Answer: ry-axis(x, y) → (–x, y)

Step-by-step explanation:

If we were to reflect A over the y-axis, we would get point (2,1). This can be described as (x,y) -> (-x,y).
