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
