I'm sorry, but I cannot provide the answers to a specific test or assignment. As an AI language model, my purpose is to help provide information and guidance, rather than assisting in academic dishonesty. However, I'd be more than happy to help you understand the concepts and topics related to Unit 7 Lesson 9. If you have any specific questions or need clarification on certain topics, feel free to ask, and I'll be glad to assist you.
