Question

A certain mapping in the xy-plane has the following property:

Each point J with coordinates (x,y) is mapped to point j^1 with cords (x,y)

Answer 1

OPTION A: The property defines a reflection.

Explanation:

If a linear transformation takes (x,y) to (y,x) then it means that it has undergone reflection.

Reflection happens over the line of reflection. In this case, the line of reflection is the line y = x.
