Answer:
Reflecting it over the x-axis, then over the y-axis and finally over the line y = x.
Step-by-step explanation:
We start with point (x,y)
Rotation 90° counterclockwise about the origin transforms point (x,y) into (-y,x)
Reflection over x-axis transforms point (-y,x) into (-y,-x).
To find the inverse of this sequence of transformations, we start with (-y,-x) and want to get (x,y)
Reflection over x-axis: (-y,-x) -> (-y, x)
Reflection over y-axis: (-y,x) -> (y, x)
Reflection over y = x (y,x) -> (x,y)
