Question

The vertices of a triangle are P(-4, 1), Q(-2, -8), and R(8, -1). What are the vertices of the

image reflected across the x-axis?

Answer 1

see explanation

Explanation:

under a reflection in the x- axis

a point (x, y ) → (x, - y ) , then

P (- 4, 1 ) → P' (- 4, - 1 )

Q (- 2, - 8 ) → Q' (- 2, 8 )

R (8, - 1 ) → R' (8, 1 )
