I'm trying to find a matrix-expression of a 30° reflection at the line $g(x)=2x+4$
Somebody can give a hint?

Sorry for the bad english. With reflection I mean http://en.wikipedia.org/wiki/Reflection_(mathematics)#Reflection_across_a_line_in_the_plane and a reflection of 30° means, that g and the $x_1$-Axis intersect with 30°. Sorry again for the bad english :-( – 2012-06-08
