What tab is this? I'm guessing a bend on the 9th fret to the 11th? Then a slide down from the 9th to the 7th. Although, I could be wrong, and probably am. Listen to the song and look at the tab and figure it out.
I think it's just a sort of visual reference as to how long the note is supposed to last.

Metalheads are the worst thing that ever happened to metal.
try looking at the bottom of the tab. maybe it will tell you what the symbols mean
