On a coordinate grid, point P is at (1, 7) and point R is at (−2, −3). Points Q and S are a reflection of both points across the x-axis. What are the coordinates of Q and S? (1 point) Q(−1, 7), S(2, −3) Q(−1, −7), S(2, 3) Q(−1, 7), S(−2, 3) Q(1, −7), S(−2, 3)

  (d)  Q(1, −7), S(−2, 3)

Step-by-step explanation:

Reflection across the x-axis negates the y-coordinate:

  (x, y) ⇒ (x, -y) . . . . reflection across the x-axis

Then we have ...

  P(1, 7) ⇒ Q(1, -7)

  R(-2, -3) ⇒ S(-2, 3)

These coordinates match the last choice.
