Say that point C is x=4, y=2 and that point D is x=3, y= 5 .
What column matrix represents the displacement from C to D?
A good answer might be:
- Finish X - Start X = 3 - 4 = -1
- Finish Y - Start Y = 5 - 2 = 3
So the column matrix is ( -1, 3 )T
Reading Displacements from Graph Paper
The first diagram shows
a vector between two points.
The numerical values can be read off of the
graph by counting the number of squares from the tail of the vector
to the tip: (-3, 5)T.

QUESTION 14:
Do that with the second diagram. What is the displacement from E to F?
