Question

The vertices of parallelogram ABCD are A(2,1),B(3,4),C(5,3), and D(4,0). ABCD is reflected over the x-axis to create parallelogram QRST. What are the coordinates of QRST?

A
Q(−2,1),R(−3,4),S(−5,3),T(−4,0)

B
Q(−2,−1),R(−3,−4),S(−5,−3),T(−4,0)

C
Q(1,2),R(4,3),S(3,5),T(0,4)

D
Q(2,−1),R(3,−4),S(5,−3),T(4,0)

Answer 1

The correct answer is:

D) Q(2,1) R(3,-4) S(5,-3) T(4,0)

Explanation:

When you reflect over the x-axis the vertices of the parallelogram, the y -coordinates is multiplying by -1.

Then the new coordinates of the parallelogram are:

Q(2,-1) R(3,-4) S(5,-3) T(-4,0)
