Question

What is the difference in the rule of reflection for a point reflected across y=x and a point reflected across y =-x

Answer 1

Answer:

see explanation

Step-by-step explanation:

Under a reflection in the line y = x

a point (x, y ) → (y, x )

Under a reflection in the line y = - x

a point (x , y ) → (- y, - x )

The difference is that for y = - x, the x and y coordinates swap places as in y = x but they are both negative.
