Answer:

(C)Angle MRN and Angle NRO

Step-by-step explanation:

A diagram of the given problem is drawn and attached below.

From the diagram:

Option A: Angle PRL and Angle LRM = Angle PRM which is not 180 degrees.

Option B: Angle ORP and Angle MRN are vertically opposite angles and are therefore not linear pairs.

Option C: Angle MRN and Angle NRO are on the line ORM and therefore forms a linear pair.

PLEASE EXPLAIN <br> I wil give brainiest
Advocard [28]

Answer: (-2, -2)

Step-by-step explanation:

Reflection over the x-axis: (x, y) → (x, -y)

(-2, 2) → (-2, -2)

x would remain the same but the y would turn negative since we're reflecting over the x-axis. The x never changes in this situation but since we're flipping it over the x-axis, they y has to be negative.

Hope this helps!
