Very good so far!
It looks like the first one that you didn't answer would be, "Yo tengo que escribir un periodico," which means that you have to write a newspaper.
2.) May be correct to your teacher, but you could also say "a las nueve" instead of "en nueve."
3.) I'm unsure of what it wants you to respond with... I'm sorry!
4.) Is correct!
5.) You may want to put "los" before "libros." It adds clarification.
6.) Is correct, muy bien!
7.) Would be "desayuno." Remember, you're talking about yourself, so you put an o at the end.
8.) Would be "escribes." Very close, though. I hope this helps.
