Hello,
A ship's movements are being tracked on a radar screen. The ship is first seen on point a with coordinates (5,8)
1. It moves along vector AB represented by the ordered pair (6,1)
2. Then it travels along vector BC represented by the ordered pair (4,3)
3. Finally, it moves along vector CD represented by the ordered pair (2,1)
Determine the final location of the ship on the radar screen.
I graphed them and I don't see a pattern. Can you help?

X location = 56+4+2 = 5
Y location = +813+1 = +5
(5,5)
