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?
Step 1- reflected in x axis (x ,y) ⇒ (x , -y)
Step 2 - rotated 90° counterclockwise = (x, -y) ⇒ (- -y , x) ⇒ ( y, x)
Step 3 -reflected in the line y = x = (y , x) ⇒ ( x , y) = image point
