```One way is the follow:

myline = Line[{{5, -5}, {5, 5}}];

Show[Graphics[{AbsoluteThickness, myline}], Frame -> {True, True,
False, False}, PlotLabel -> "graph 1", FrameLabel -> {"x", "y"}, Axes
-> {True, False}, AxesStyle -> AbsoluteDashing[{2, 4}], PlotRange ->
{{0, 10}, {-6, 6}}];

lstlines = (Line[{{#1, -5}, {#1, 5}}] & ) /@ Range[-10, 10];
Show[Graphics[{AbsoluteThickness, lstlines}], Frame -> {True, True,
False, False}, PlotLabel -> "graph 1",  FrameLabel -> {"x", "y"}, Axes
-> {True, False}, AxesStyle -> AbsoluteDashing[{2, 4}], PlotRange ->
{{-10, 10}, {-6, 6}},
ImageSize -> {400, 300}];

Here is some useful links for Mathematica graphics

http://library.wolfram.com/infocenter/TechNotes/263/
http://library.wolfram.com/infocenter/Conferences/179/
http://library.wolfram.com/infocenter/Conferences/181/

The last two belong to Tom Wickham-Jones the author of the very good
book
Mathematica Graphics: Techniques & Applications
http://library.wolfram.com/infocenter/Books/3753/

But read carefully the relevant material from the Mathematica Book

http://documents.wolfram.com/mathematica/book/section-2.10

Also keep in touch with this forum with so many kind Mathematica
experts!
