Answer:
B (4, 1)
Step-by-step explanation:
When you rotate 90 degrees about the origin you do (x,y) ----> (y, -x)
So let's do that first to your points.
(-4, 1) -----> (1, 4)
Now we have to do y = x you do this (x,y) ---> (y, x)
All we have to do now is switch them again.
(1, 4) ----> (4,1)
Hope this helps ya!!
