Question

Find A’ and B’ if A (-1,-9) and B (2,3) is reflected over the x-axis

Answer 1

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

For point A (-1, -9), the x-coordinate remains -1, but the y-coordinate changes its sign. Therefore, point A' is (x, y) = (-1, 9).

For point B (2, 3), the x-coordinate remains 2, but the y-coordinate changes its sign. Therefore, point B' is (x, y) = (2, -3).
