eodi sarayo? (어디 살아요?) it just means "where do you live?". but there's no subject in the korean sentence. subjects are more often omitted in korean sentences if they(subjects) can be easily figured out from the context of the conversation. so the sentence can also be "where does she/he/it?" in English. '어디' is 'where' or more like 'which place' in English. it's used here as an interrogative pronoun in terms of English grammer to me but as a demonstrative pronoun in Korean grammer according to the standard korean dictionary. ^^ '살아요' is made up of two parts; the stem of the verb '살' from the uninflected form of the verb '살다' and the ending word '아요'. '살다' is the verb, 'live' in English. '아요' is the ending of the verb that sounds informal but shows a bit of respect to the hearer. simply you can use this sentence, '어디 살아요?' to ask someone where they live with some respect for the hearer. 'Inchen sarayo' (인천 살아요) can be literallay translated into "(an omitted subject) live in Inchen". Inchen is a big port city which is close to Seoul, the capital of Korea. so the conversation goes as follows. 어디 살아요(eodi sarayo)? ㅡㅡㅡㅡ which place(where) do(es) (an omitted subject) live? 인천 살아요(inchen sarayo). ㅡㅡㅡㅡ (an omitted subject) live(s) in Inchen.

sarayo, whose pronunciation reminds me of korean, means I love you.
