Sure, but one or more of the numbers would have to be negative.
In that case, even the mean could be zero.

Answer:
(2,-9)
Step-by-step explanation:
A reflection around the x-axis implies keeping the x-coordinate as it its (no change in its numerical value), while using the exact opposite of the numerical value of the y coordinate.
In our case then:
X coordinate unaltered = 2 stays as 2
Y coordinate opposite of the original value: 9 changes to "-9"
Therefore the coordinates of point A' are: (2,-9)
