Option B (x,y) (x,-y) is correct answer.
Step-by-step explanation:
We need to identify which rule describes a transformation across the x-axis.
The transformation rule across the x-axis states that the reflection across x-axis the x-coordinate remains the same, while the y coordinate becomes opposite of the given value.
if we have (x,y) then transformation across x-axis will be (x,-y)
x-coordinate remains the same while y-coordinate sign has been changed.
So Option B (x,y) (x,-y) is correct answer.
