little notation issue

I have a (probably) very simple question...

On the image above what does the little diagonal line on the bottom half between the G note and A&F notes mean. If it is indeed a slide, which i find unlikely, how can you slide from an open G to an F, since that note is not exactly close from the open G

So what does this diagonal line mean, and if it a slide... how do you do that?

My teacher gave me this piece of music as a study for the first position, so i have to play this in first position.

it could be the notes are tied together or a slur

I think Brew's on to something.
It's been 25 years since I studied classical guitar in college but I actually recollect seeing that.
I 'think' that indicates that you don't damp the G until the last possible instant before striking the F and A. Or ... it's a misprint and the G should be played on the 4th string fifth fret.

Whatever it is, it is non-standard. I vote for three possibilities:

1. Slide or gliss from 4th string G to F. However, glisses often use the word gliss.

2. It is a non-standard slur. You would need to look at the rest of the music to see if traditional slurs are used. If so, then this is not a slur. Also, it is not highly common to strike the open 3, then hammer-on the F. Usually hammer-ons are done on one string.

3. Another possibility is that the F is a melodic continuation from the preceding G. I haven't seen this symbol used this way, but who knows?

Let us know more when you find out anything.

I'd say it was a slide from the 5th fret of the D string to the 3rd fret and when you reach the third fret you add the A on the second fret of the G string. It really doesn't show whether it is to be a hammer on or to pluck both strings or actually just use the slide to sound the two notes G to F (2 fret slides sound right nice to me) and pluck the A note on the G string which would work well too.

Check the bar before and after - looks like 2 parts to me - an ascending line with the stems up and the F (played with p?) is a bass note - in which case the diagonal implies the splitting of a the G to F and A (which is unusual - and you'd expect up and down stems on the G) or its a typo...
