Interesting question. I had this issue when I first picked up basketball. Playing on the slanted driveway is a pretty common quandary for many of us. I would say, considering the hoop is on the higher end of the driveway, that you’ll be fine. Its better to practice shots on a higher hoop than a lower one. It’ll help with your trajectory and overall strength on your jump shot.
Just try and get a little run on a regularly balanced court once in a while.
