Chapter 2.1, Problem 23E

Let $u=\left[\begin{array}{c}1\\ 3\end{array}\right]$ and $v=\left[\begin{array}{c}2\\ -2\end{array}\right]$, and let $A$ denote the point $\left(-2,1\right)$.

a) Find points $B$ and $C$ such that $u=\stackrel{\to }{AB}$, $v=\stackrel{\to }{AC}$, and $u-v=\stackrel{\to }{CB}$.

b) Graph $u=\stackrel{\to }{AB}$, $v=\stackrel{\to }{AC}$, and $u-v=\stackrel{\to }{CB}$.
