Question

What is the ordered pair for A' if A(2,-3) is reflected over the line y = x?

Answer 1

We are asked to determine the coordinates of a point that is reflected over the line y = x. Let's remember that when we reflect a point (x,y) over y = x, we get the following result:

$R_{y=x}(x,y)=(y,x)$

Therefore, when we reflect the point (2,-3) we get:

$R_{y=x}(2,-3)=(-3,2)$
