Question

Find the coordinates when the parallel lines AB and PQ are reflected over the x-axis. The points are A(1, 1), B(1,4), and

P(3, 1). Q(3, 4).​

Answer 1

see explanation

Explanation:

Under a reflection in the x- axis

a point (x, y ) → (x, - y )

Hence

A(1, 1 ) →A'(1, - 1 )

B(1, 4 ) → B'(1, - 4 )

P(3, 1 ) → P'(3, - 1 )

Q(3, 4 ) → Q'(3, - 4 )
