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 = -5-6+4+2 = -5
Y location = +8-1-3+1 = +5
