Answer:
(5,-2).
_______________________
South is Negative Y axis.
East is Positive X axis.
(look at the compass in the top right corner)
Cory's current coordinates are (1,1).
When Cory walks 3 units south, he moves 3 steps downwards in the Y axis, which means if his current Y position is 1, we subtract 3, ( 1 - 3 = -2).
And when Cory moves 4 units east, Add 4 as he is walking in the positive X axis. (4 + 1 = 5).
new (x,y) are (5,-2).
