Question

What are the coordinates of the point (−1, 6) after a reflection across the x-axis

Answer 1

(-1,-6)

Explanation:

Because it is reflecting across the x-axis, the x value remains the same but the y value moves down the axis the same distance it was, meaning that the y part of the coordinate becomes the opposite.

For example, if (1,2) was reflected across the x-axis, it becomes (1,-2).
