Answer:
(-1,1)
Step-by-step explanation:
The 270° counterclockwise rotation about the origin is equivalent to a 90° clockwise rotation.
Now, if a point P(h,k) is rotated 90° clockwise about the origin then the final point P' will have coordinates (k,-h).
In our case, the point is P(-1,-1) and it is rotated by 270° counterclockwise about the origin and finally, the position of the point will be (-1,1). (Answer)
