If an ordered pair is reflected on x-axis, it will result in opposite number of y. If the original y positive, the reflected point of y will be negative.
we can write it as
(x,y) -> reflected to x axis -> (x, -y)
Solution:
(x,-y) = (4.75, -2.25)
(x,y) = (4.75, 2.25)
The original point was (4.75, 2.25)
