It just depends on what you are trying to play, its too vague to just give us the tab and let us guess, as most times on music, tablature isnt sufficient nor it should be, every musician must have it's own interpretation of the tablature and of the song itself, if you're playing a cover and want to play exactly like on the record, listen to it and just play like the original, you will notice if it is a bend, a hammer on, a slide or a pull off...
By just looking at the tab, i would say that the best thing to do there would be to slide, like, you hold the note on the 10th fret G String and slide into the 11th on the B.
You can also try to hold the 10th G (i would use my index finger) and slide with another finger (here i would slide with the middle finger) to the 11th B, but then again, i dont know the song and i cant help you much further with this, it isnt just a simple "i dont know what this symbol means" it's the interpretation of the symbol and how it interacts with the song.
Bottom line: Just listen to the song and try multiple option until you get the one that sounds right
Hope this helped, happy playing :)
