Line segment AB is shown on a coordinate grid: A coordinate grid is shown from positive 6 to negative 6 on the x-axis and from positive 6 to negative 6 on the y-axis. A line segment AB is shown with A as ordered pair 1, 3 and B as ordered pair 5, 3. The line segment is reflected about the y-axis to form A′B′. Which statement describes A′B′? (4 points) A′B′ and AB are perpendicular. A′B′ and AB are equal in length. A′B′ is half the length of AB. A′B′ is greater than twice the length of AB.
