What can I do about my teacher?

Everyone in her classroom is having troubles understanding and we have told her that and this is her response to when we say that we don't understand. You don't understand because you ever pay attention. She says it and it makes a lot of her students upset because they have been working so hard to make a good grade in her class and she doesn't even care enough to teach the class. So we are try to teach ourselves something that we have no idea how to do. I've done everything that I can to pass that class and my average right now is a 61 and I write down everything that she tells me to and she gives us a test almost everyday and the reason we are failing it is because she isn't teaching it well to where we can understand it. She told a student today when he said Mrs. Leatherman I don't understand will you please explain it. Her responce was. Your stupid if you don't understand this. I was so angry. I just wanted to get up and walk out because like I told one of my friends that I'm so sick of her calling the whole class stupid when everyone in there is capable of passing her class if she would just stop complaining about how bad we are and how to her we never pay attention when there is a lot that do and I'm one of them then we can succeed in her class but she failed almost all of her class last semester it's because she is more worried about basketball and volleyball than teaching. I've never in my whole time going to school had a teacher like her that's not willing to explain anything and no willing to let us ask questions without her saying that we don't pay attention or we don't try. The whole class is failing. I personally want something done about this. I've done everything that I can do. I've even told her that she needs to step up and help us to pass her class but nothing is getting through to her. I've been told that they will not fire her because she is a coach but to me if she is going to treat her students like trash and disrespect us then that should be enough to get her fired. The students at West Lincoln High School has had enough of her telling us that we are stupid and that we don't pay attention and that we don't try.
