Answer:
(23,-23)
Step-by-step explanation:
If company programmed rozo to walk 3 yards east and 4 yards north each minute, then after 7 minutes rozo walked 3·7=21 yards east and 4·7=28 yards north.
On the coordinate plane north direction is moving down and east direction is moving to the right.
Since rozo walked 21 yards to the right and 28 yards down, then its coordinates became (2+21,5-28)=(23,-23).
