Reflections Across the x- or y- Axis Quick Check
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′ ?(1 point)
A′(4,−1), B′(5,−2), and C′(10,−1)
A′(−4,1), B′(5,−2), and C′(−10,1)
A′(4,1), B′(5,2), and C′(10,1)
A′(−4,1), B′(−5,2), and C′(−10,1)

Triangle ABC is reflected across the x-axis, which means that the y-coordinate of each point should be negated. So the correct answer is A′(−4,1), B′(−5,2), and C′(−10,1).
