Question

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)

Answer 1

[AI-generated answer — Bot GPT 3.5]

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).
