Triangle ABC is reflected across the x-axis. If the coordinates of the original shape are A (-4, - 1), B (-5, -2), and C (-10, — 1), what are the coordinates of A', B', and C"?
The reflection across the x-axis simply changes the sign of the y-coordinate of each point. Therefore, the coordinates of A' would be (–4, 1), B' would be (–5, 2), and C' would be (–10, 1).
