The coordinates of the point where the passenger was dropped of is the point (2, 2).
(1, 2) + (3, 1) = ((1 + 3), (2  1)) = (4, 3)
(4, 3) + (6, 5) = ((4  6), (3 + 5)) = (2, 2)

Answer: The coordinates of the point where the passenger was dropped are (2, 2).
Stepbystep explanation: Given that a taxicab starts at (1, 2) on the grid. It goes 3 blocks east and 1 block south to pick up a passenger.
After that, it goes 6 blocks west and 5 blocks north and drops off the passenger.
We are to find the coordinates of the point where the passenger was dropped off.
3 blocks East: When the taxicab goes 3 blocks east, then the the coordinates of the point becomes
(1, 2) ⇒ (1+3, 2) = (4, 2).
1 block South: When the taxicab goes 1 block South, then the the coordinates of the point becomes
(4, 2) ⇒ (4, 21) = (4, 3).
6 blocks West: When the taxicab goes 6 blocks West, then the the coordinates of the point becomes
(4, 3) ⇒ (46, 3) = (2, 3).
5 blocks North: When the taxicab goes 5 blocks South, then the the coordinates of the point becomes
(2, 3) ⇒ (2, 3+5) = (2, 2).
Thus, the coordinates of the point where the passenger was dropped are (2, 2).
