Question

Identify the reflection of the figure with vertices P(−11,−13), Q(−17,19), and R(23,−27) across the x-axis.

P (−11, 13), Q (−17, −19), R (23, 27)
P (11, 13), Q (17, −19), R (−23, 27)
P (11, −13), Q (17, 19), R (−23, −27)
P (−13, −11), Q (19, −17), R (−27, 23)

Answer 1

P (−11, 13), Q (−17, −19), R (23, 27)

Explanation:

Got it right on my test :)

Answer 2

P (−11, 13), Q (−17, −19), R (23, 27)

Explanation:

we know that

The reflection of a figure across the x-axis has the following rule

(x,y) -----> (x,-y)

so

P(-11,-13) -----> P(-11,13)

Q(-17,19) -----> Q(-17,-19)

R(23,-27) ----> R(23,27)
