Latin had a few ways to affirm or negate. Both "ita" (it is) and the more forceful "ita vero" (it is true) could be used for yes, but you could also repeat the verb from the question with modification to affirm. "Have you eaten?" -> "I have eaten." For negation you could do the same verb-repeating, but add "non" to negate.
