Answer 2

Option A is correct.

The ordered pair is the reflection of (3, 10) across the x-axis is

`(3, -10)`

Explanation:

The rule of reflection across the x-axis is given by:

`(x, y) \rightarrow (x, -y)`

As per the statement:

reflection of (3, 10) across the x-axis

Apply the rule;

`(3, 10) \rightarrow (3, -10)`

therefore, the ordered pair is the reflection of (3, 10) across the x-axis is

`(3, -10)`
