Answer:
(4,1)
Step-by-step explanation
1. A (-4,1)-> Original
2. I am going to assume it is 90 degrees counterclockwise since it is not specified. The formula is (-y,x)-> (-1,-4)
3. The formula is (-y,-x)-> (4,1)
I think it is (4,1) but I am not a hundred percent sure since I am also a geometry student.
