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
