Point A (4, -7) is reflected in the x-axis. Identify the coordinates of its image after this reflection.

Question

The coordinates of A' are (_, _)

Answer 1

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

For point A (4, -7):

• The x-coordinate is 4.
• The y-coordinate is -7, which becomes 7 after reflection.

Thus, the image of point A after reflecting in the x-axis is A' (4, 7).

The coordinates of A' are (4, 7).
