ANSWER:
(10, -15)
EXPLANATION:
Given:
The point (10, 15)
To find:
The reflection across the x-axis
Note that when a point P(x, y) is reflected across the x-axis, the image will be P'(x, -y)
Therefore, if the (10, 15) is reflected across the x-axis, the image will be (10, -15).
The reflection of the point (10, 15) across the x-axis is (10, -15)
