A simple array will do:

enter image description here

documentclassarticle

usepackageamsmath,amssymb

begindocument

[
 beginarray r l 
 & p rightarrow q \
 & p \
 cline2-2
 therefore & q
 endarray
]

enddocument

If you want a coloured rule, add colortbl to your preamble and use:

enter image description here

[
 beginarray r l 
 & p rightarrow q \
 & p \
 arrayrulecolorredcline2-2
 therefore & q
 endarray
]

Depending on how much extension you want on the line...two ways are shown.

The thickness of the rule is determined by the value of fboxrule.

Depending on how much extension you want on the line...two ways are shown.

The thickness of the rule is determined by the value of fboxrule.

 & p rightarrow q&\
