'Eres' would be the answer for both.
“Usted” is generally
more formal, while “tú” is a more formal use of the Word you. You would use
usted when referring to teachers, people of authority, and your elders, while
tú is more appropriate for friends and family members.
I think tú form ends in an s when you use it, such as “tú hablas”, meaning you
talk. It seems like the usted form just ends in the vowel of that verb, like in
the 3rd person, for example “usted habla”
