The point (x,y) is first reflected in the x-axis then rotated 90 degrees counterclockwise about the origin, then reflected in the line y = x . What is the image point?
(x , y) reflected in x axis = ( x , - y)
(x, -y) after 90° counterclockwise rotation = ( y, x)
(y, x) reflected across y = x = ( x, y)
