The final vector when more than one vector is combined
For example, for the coordinates A(2,3) and B(6,6) we can find two different ways:
1. Go directly from A to B which is
2. Use the position vectos, so go from A to O and O to B
is the resultant vector

Similarly, this works if we don't have position vectors or can't write the position vectors.
Say we know and
How would we write ?

By finding the resultant vector, we can find the distance between any two points.*NOTE: You can use the distance formula here too!

Collinear Points
A
B
C
What are two important ideas that are true about AB and AC
that we could use to determine if points A, B and C are collinear?
1.
2.
Now, extend this to vectors!
