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  the  x  axis  →  (x, -y)

 

(x, -y)   rotated 90°  counter-clockwise  →  (y, x)

 

(y , x)   reflected in the line y = x  →  (x , y) = image point
