First draw a coordinate system in $\mathbb R^2$ (might as well be rectangular)...

anonymous · Answer

the vector you are given I am reading as$$\vec x_1=\langle-2,3\rangle$$which is a vector that point from the origin to the point $(-2,3)$ so draw that in.
make sure the point of the arrow is on the point specified.

um, no it said on the worksheet x1= [-2]
                                                      [ 3]. The bracket covers the entire -2 and 3.

anonymous · Answer

the way you write it makes very little difference

anonymous · Answer

$$\vec x_1=\left[\begin{array}1-2\3\end{array}\right]=\langle-2,3\rangle=-2\hat i+3\hat j$$all equivalent

okay
