Question

The coordinate P(−2,7) is reflected over the y-axis. State the coordinate of P'.

A. P' (2.7)
B. P' (-2, -7)
C. P' (7,2)
D. P'(2, -7)

Answer 1

To reflect the point P(−2, 7) over the y-axis, you change the sign of the x-coordinate while keeping the y-coordinate the same.

So, the reflection of P(−2, 7) over the y-axis will be P'(2, 7).

Therefore, the correct answer is:

**A. P' (2, 7)**.
