In a coordinate plane, quadrilateral PQRS has vertices P (0,7), Q (4, 6), R (2, 3), and S(-1, 3). Find the coordinates of the vertices of the image after a reflection across the x-axis.

i think the answer is b.

step-by-step explanation:

not 100% sure though.

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
