Use graph paper to complete the following problems.  

1. Draw $\vec { \text{a} }= 2\textbf{i} + 3\textbf{j}$ , $\vec { \text{b} }= \textbf{i} – \textbf{j}$, and $\vec {\text{c}}= –3\textbf{i} + 2\textbf{j}$.

2. Draw $\vec { \text{a} }+ \vec{\text{b}}$ on the graph paper.

3. Write $\vec { \text{a} }+ \vec{\text{b}}$ in $\bf\text{i, j}$ form.

   Step (c):

   $2\textbf{i}+3\textbf{j}+\textbf{i}−\textbf{j}$

4. Write $\vec { \text{b} }+ \vec{\text{c}}$ and $\vec { \text{c} } – \vec{\text{a}}$ in $\bf\text{i, j}$ form without drawing them.

   Steps (d):

   $\text{b}+\text{c}=\textbf{i}−\textbf{j}+(−3\textbf{i}+2\textbf{j})$
   $\text{c}−\text{a}=−3\textbf{i}+2\textbf{j}−(2\textbf{i}+3\textbf{j})$
