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 .

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=

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} =
