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?

A. rx-axis(x, y) → (–x, y)

B. ry-axis(x, y) → (–x, y)

C. rx-axis(x, y) → (x, –y)

D. ry-axis(x, y) → (x, –y)

Answer 1

Answer:

• B. Ry-axis(x, y) → (–x, y)

Step-by-step explanation:

As per the graph we see that:

• Reflection over y-axis, y- coordinates remain as is, x- coordinates change to opposite

So the rule is:

• Ry-axis (x, y) → ( - x, y)

Correct option is B

Answer 2

Answer:

B. ry-axis(x, y) → (–x, y)

Step-by-step explanation:
