Can I beat my dwi if I barley blew over the legal limit 0.009 also charge with an open container

Absolutely. You could have been in absorption, meaning that your bac at time of driving was lower than when thr test was taken - later, and after driving had stopped. Also, when its that close, you can't trust a machine like that to be that precise and reliable on a breath test. Hire a dwi lawyer that knows how to win dwi cases, and yes, a low bac, even over .08, can be won.
