Question

4. Vertex A of triangle ABC is located at the

point (2,5). Which transformation moves
vertex A to the point (-2,5)?

A reflection across the x-axis
B reflection across the y-axis
© (x,y) → (x+4, y)
D (x,y) - (x - 4, -y)

Answer 1

Explanation:

Let's try each choice and see which one ends up having the point (-2, 5)

Option A: (2, 5) → reflection across x-axis → (2, -5)

Option B: (2, 5) → reflection across y-axis → (-2, 5)

Option C: (2, 5) → (x + 4, y) → (6, 5)

Option D: (2, 5) → (x - 4, -y)→ (-2, -5)

As we can see from all of the options, the correct answer is letter choice B.
