Would this wide black line mean I would have to replace digitizer and glass or just one of them? The touch screen still works.

A black line down the screen would likely indicate the LCD is broken, so you’d have to replace the LCD display itself. If glass is broken, you’ll want to replace that; if not, then don’t. If touch is still working, then the digitizer is not broken. I’m not familiar with that model, but depending on the tablet some devices have the entire LCD + digitizer + glass as one assembly, whereas some have the digitizer + glass separate from the LCD. If that tablet has a single display assembly, you’d need to replace the entire thing; if it has a separated assembly you could possibly get away with replacing just the LCD (assuming the glass isn’t broken).

you cracked the screen in that spot can’t fix that you can still see out of it right?
