Someone plz help me and explain how to do it!!

Answer: The answer is -8, 5. Because it is reflecting, it is basically looking at a mirror. Instead of 8 being 8, 8 becomes -8, and -5 becomes 5. If you wouldn't mind, may I have brainliest, unless of course, someone else has a better explanation than mine...
Step-by-step explanation:
Answer:
X'(8 , 5)
Step-by-step explanation:
Reflection in the x -axis: x will stay the same and y will become opposite
The rule for a reflection over the x -axis is (x,y)-->(x, -y)
In this case
X(8, - 5) ---> X'(8, -(-5)) = X'(8, 5)
Answer
X'(8 , 5)
