What's the difference between toi and tu?

Ca va bien, et toi?
Ca va bien, et tu? (is this one even correct? lol)

Can you use "toi" in the same informal capacity as "tu'? Are they interchangeable?

Thank you.

Answer

tu and toi don't belong to the same category. tu is the subject of the verb and toi is a pronom tonique you can use it with prepositions like et/chez/pour etc... you can't use toi instead of tu or tu instead of toi. you can use both to do an emphasis in your sentence like : toi, tu vas bien ?
