Answer 1

I showed you how to do this earlier. Here is a link. We don't do all of your work for you but we try to help you understand the problem. Rather than posting a note to post the correct answer, it would be far better, if you still don't understand, to follow the instructions as given, then tell us what you don't understand about the next step.
