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

Answer 1

When a point 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 \(-2\) changes to \(2\).
• The y-coordinate \(7\) remains the same.

Therefore, the coordinates of \( P' \) after reflection over the y-axis are \( P'(2, 7) \).
