Question

Which set of points represents the reflection across the x-axis of the points P'(-2,-4), Q'(2, -5), and R'(-1,-8)?

A) P(-2, 4), Q'(2,5), and R'(-1,8)
B) P(2, -4), Q*(-2,-5), and R'(1, -8)
C) P'(2, 4), Q'(-2,5), and R'(1, 8)
D) P(2, 4), Q(2,5), and R(-1,8)

Answer 1

The correct set of reflected points across the x-axis for P'(-2,-4), Q'(2, -5), and R'(-1,-8) is P(-2, 4), Q(2, 5), and R(-1, 8), which is option A.

Step-by-step explanation:

To determine which set of points represents the reflection across the x-axis of the points P'(-2,-4), Q'(2, -5), and R'(-1,-8), we need to reflect each point over the x-axis. Reflecting a point over the x-axis involves changing the sign of the y-coordinate while keeping the x-coordinate the same. Therefore, the reflected points will be P(-2, 4), Q(2, 5), and R(-1, 8), which corresponds to option A.
