The coordinate point Q

Question

(-2,2) is reflected over the y-axis. Identify the x and y coordinates of Q′

Answer 1

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

For the point \( Q(-2, 2) \):

• The x-coordinate is -2, which will change to \( 2 \) after reflection.
• The y-coordinate remains \( 2 \).

Thus, the coordinates of \( Q' \) after reflection over the y-axis are \( Q'(2, 2) \).
