Responses

P′(2,7)
upper P prime left parenthesis 2 comma 7 right parenthesis

P′(7,2)
upper P prime left parenthesis 7 comma 2 right parenthesis

P′(2,−7)
upper P prime left parenthesis 2 comma negative 7 right parenthesis

P′(−2,−7)

Answer 1

When a point is reflected over the y-axis, the x-coordinate changes its sign, while the y-coordinate remains the same.

Given the point \( P(-2, 7) \):

1. Change the sign of the x-coordinate: \(-2\) becomes \(2\).
2. The y-coordinate remains the same: \(7\).

Thus, the reflected point \( P' \) is \( (2, 7) \).

So the correct response is:

**P′(2,7)**
