Question

The coordinate P(−2,7) is reflected over the y-axis. State the coordinate of P′ .(1 point) Responses P′(−2,−7) upper P prime left parenthesis negative 2 comma negative 7 right parenthesis P′(2,−7) upper P prime left parenthesis 2 comma negative 7 right parenthesis P′(7,2) upper P prime left parenthesis 7 comma 2 right parenthesis P′(2,7)

Answer 1

When a point \( P(x, y) \) is reflected over the y-axis, the x-coordinate changes sign, while the y-coordinate remains the same.

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

- The x-coordinate \( -2 \) becomes \( 2 \).
- The y-coordinate \( 7 \) remains \( 7 \).

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

So the correct response is: \( P'(2, 7) \).
