The figure below shows four named points $A$ , $B$ , $C$ , and $D$ on a grid generated by two vectors $\mathbf{v}_1$ , $\mathbf{v}_2$ in $\mathbb{R}^2$ .

Part 1

Write each point as a sum of scalar multiples of $\mathbf{v}_1$ and $\mathbf{v}_2$ . Enter v1 for $\mathbf{v}_1$ and v2 for $\mathbf{v}_2$ .

$A=$

$B=$

$C=$

$D=$

Part 2

Write each vector as a sum of scalar multiples of $\mathbf{v}_1$ and $\mathbf{v}_2$ . Enter v1 for $\mathbf{v}_1$ and v2 for $\mathbf{v}_2$ .

$\overrightarrow{CA} =$

$\overrightarrow{BA} - \overrightarrow{DA} =$

$\overrightarrow{BA} - \overrightarrow{DA} + \overrightarrow{DC} =$

$\overrightarrow{AB} + \overrightarrow{BC} + \overrightarrow{BA} - \overrightarrow{DC} =$
