Question

What ordered pair is the reflection of (3, 10) across the x-axis?
A. (10, 3)
B. (−3, 10)
C. (3 −10)
D. (−3, −10)

Answer 1

Answer:

C. (3, -10)

Step-by-step explanation:

If you place this coordinate on a graph, you will see that it reflects the coordinate (3, 10).

Answer 2

Answer:

C. (3 −10)

Step-by-step explanation:

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

(3,10) → (3,-10)

So, the answer is C. (3 −10).
