How to delete email from facebook login?

[Alyssa]

I've had multiple emails, and when I go to log onto facebook, they all come up, in the login box, and I can choose from the one I want to login. How can I delete the ones that I no longer use/need. I am on google chrome on a macbook pro. I've deleted my history multiple times, and I've tried the while shift + delete, but neither of those have worked. Thanks!
