Ataxicab starts at (1, -2) on the grid. it goes 3 blocks east and 1 block south to pick up a passenger. then it goes 6 blocks west and 5 blocks north and drops off the passenger. what are the coordinates of the point where the passenger was dropped off?

(x,y)
east is an increase in x
west is a decrease in x
north is an increase in y
south is a decrease in y

so
3 east (x+3)
1 block south (y-1)
6 blocks west (x-6)
5 blocks north (y+5)

so in total, x+3-6 and y-1+5
basically x-3 and y+4
minus 3 from  and add 4 to y
(1,-2)
(1-3,-2+4)
(-2,2) is the dropoff point
