Answer:
(B)(0,5)
Step-by-step explanation:
Given the start point at (4,1)
Given the (x,y) coordinates
- Moving to the left 4 places is: x-4
- Moving up 4 places: y+4
Therefore, applying the rule to (4,1), we have:
(4-4, 1+4)=(0.5)
The coordinates of the new ordered pair is (0,5).
The correct option is B.
