The point is 2 units above the line y = 3, so its image lies 2 units below it, at (2, 1). The x-coordinate is unchanged.

Which points are invariant under a reflection in the line y = −2?
Reflection
The point (3, −4) is reflected in the x-axis and its image is then reflected in the line x = 1. Find the final coordinates.
Reflection
Find the image of the point (−1, 4) when reflected in the line x = 2.
Reflection
The point P(a, b) is reflected in the x-axis to P'(3, −5). Find a and b, and then find the image of P in the origin.
