Question

Points P is at (2, 1) and point R is at (-6, -5). Points Q and S are reflections of both points across the x-axis. What are the coordinates of Q and S?

A. Q (2, -1), S (-6, 5)
B. Q (-2, 1), S (6, -5)
C. Q (-2, -1), S (6, 5)
D. Q (-2, 1), S (-6, 5)

Answer 1

To find the reflection of a point across the x-axis, keep the x-coordinate the same and change the sign of the y-coordinate.

Step-by-step explanation:

To find the reflection of a point across the x-axis, we keep the x-coordinate the same and change the sign of the y-coordinate.

In this case, the coordinates of point P are (2, 1), so the reflection of P across the x-axis, Q, would have the coordinates (2, -1).

Similarly, the coordinates of point R are (-6, -5), so the reflection of R across the x-axis, S, would have the coordinates (-6, 5).

Therefore, the coordinates of Q are (2, -1) and the coordinates of S are (-6, 5).
