1) The vector $\displaystyle {\overrightarrow{v}} = [-6, -2]$ has tail $\displaystyle A$ and head $\displaystyle B$. Graph each point $\displaystyle A$, and determine the coordinates of $\displaystyle B$.

a) $\displaystyle A(8, 5)$

How would I find the coordinates of B for the question? Do you find it by adding the $\displaystyle x$ values together and the $\displaystyle y$ values together?

So. . .the coordinate of B for a) is. . .

$\displaystyle B(2, 3)$?

2) Point $\displaystyle A(5, -3)$ is the head of vector $\displaystyle {\overrightarrow{v}}$. Graph each vector $\displaystyle {\overrightarrow{v}}$ and determine the coordinates of its tail.

a) $\displaystyle {\overrightarrow{v}} = [8, -5] $

Do I subtract the coordinate values with one another, so the tail of letter a is $\displaystyle (3, -2)$?
