When writing dialogue, with what type of speech would you be most likely to use slang?
formal
informal
casual

You would write it in the casual form. You wouldn't write it informal because it would sound too unprofessional. And making it formal, well, some people wouldn't understand if you were to write in the formal way. They wouldn't understand the words. So just the casual way would do.

I'm sorry but i'm not for sure what you need on

Idk you definitely don’t give me 15 points it say 8.
