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)
