Question

The coordinates of point A are (-3a,4b). If point A' is the image of point A reflected over the line y = x, what

are the coordinates of A?

Answer 1

Answer: (4b, -3a)

Reason:

When reflecting over the line y = x, we swap the positions of the x and y coordinates.

The reflection rule is
`(\text{x},\text{y}) \to (\text{y},\text{x})`

As an example:
`(2,3) \to (3,2)`
