[Tex/LaTex] Undefined control sequence – \psset

pstricks

I am trying to build the image on this page:

enter image description here

When I execute "tex Cartesian_coordinates_2D.tex" eventually I get the error:

! Undefined control sequence.
\psaxes@vii ... \pst@dimd {#6}\pst@dima =\dimexpr
                                              \pst@dima -\pst@dimg \rela...
<to be read again>
               \psset
l.8 \psset
      {linewidth=.4pt}
?

This is the first time I've used Tex so I don't know what to do.

This is TeX, Version 3.14159265 (MiKTeX 2.9.6100 64-bit)
Windows 7 Pro x64

[edit]

Alternately, when I try to run the script in Texworks I get the following error:

! Package xkeyval Error: xkeyval loaded before \documentclass.
See the xkeyval package documentation for explanation.
Type  H <return>  for immediate help.
 ...                                              

l.62 ...yval loaded before \protect\documentclass}
                                              %

You need to compile this with either latex > dvips > ps2pdf or xelatex:

\documentclass{article}

\usepackage{pst-node,pst-plot}

\begin{document}

\psset{linecolor=black,linewidth=1pt,arrowsize=8pt,unit=0.29cm}
