For reflection in the x-axis, change the sign of the y-coordinate of every point.For reflection in the y-axis, change the sign of the x-coordinate of every point.
reflection in the x-axis
Reflection across the y-axis changes the sign of the x - coordinate only, that is, (x, y) becomes (-x, y).
It is: (1, -5) reflection across the y axis
In transformations a reflection across the x axis produces a mirror image
y' = y, x' = -x.
For a reflection across the x axis, both the slope and the y intercept would have the same magnitude but the opposite sign.
If your points are (p,f), they become (p,-f).
y = -f(x) is a reflection of y = f(x) in the x axis.
Example: if you have a point with the coordinates (2,4), a reflection over the y-axis will result in the point with coordinates (-2,4).

Rotation is a transformation that spins an object on a specific point. In Adobe Illustrator, an object's default rotation point is its centre.Reflection is a transformation that flips an object over and across a specific axis. In Adobe Illustrator, an object's default reflection axis runs vertically through its centre.
It will be where it was, to start with.
