Can someone help draw the resultant vector 3b-4a

1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

+close

3. Feel free to nominate the person for helper of the week in #helper-nominations
4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

Draw 3b, draw 4a, then subtract.

How would I subtract graphically?

[slow elk]

Note that u - v = u + (-v).

Like this?

[slow elk]

No.
When you add vectors, the endpoint of the first one must coincide with the initial point of the second one.
So, like this.

[sick cedar]

Both vectors a and b are going in the same direction. I would just put the initial point of b on the terminal point of a to create a longer vector?

[slow elk]

Yes.
If two vectors are collinear, then all of their linear combinations are also collinear to them both.
