Question

, with vertices A(–3, 5), B(–2, 2), and C(–4, 3), is reflected across the y-axis. A student determined one of the the vertices on the image to be (2, 2). Evaluate the student's answer.

Answer 1

He refelected B, reflecting over the y-axis changes the x value (x,y) -> (-x,y)

Answer 2

Student's answer is correct.

Explanation:

Given : Vertices A(–3, 5), B(–2, 2), and C(–4, 3), is reflected across the y-axis. A student determined one of the the vertices on the image to be (2, 2).

To find :Evaluate the student's answer.

Solution : We have given that Vertices A(–3, 5), B(–2, 2), and C(–4, 3).

Vertices are reflected across the y axis

By the reflection rule across y axis (x ,y) →→→ (-x ,y).

Then All the vertices would be A(–3, 5) →→ ( 3, 5)

B(-2,2) →→ ( 2, 2)

C(-4 ,3) →→ ( 4, 3).

Therefore, Student's answer is correct.
