i need some advise on how to play and construct jazz lines i will be very grateful if i can get an answer
Well, that is a very broad question, considering that jazz is a very deep genre to play, it takes a long time (Possibly years) before you even start sounding like a real jazz musician. I know this doesn't help your situation very much...

Well I guess you could start by listening to jazz a lot. Like being one of the main genres you listen to. I know that sounds like over kill, but it trains your ear and gives you ideas. Also you can transcribe some solos of famous jazz musicians to get some ideas. By seeing how jazz musicians play over certain chords and progressions, you get a deeper understanding of how to play jazz.
