How do you pronounce Wie geht es Ihnen?

Wie bist du is the literal translation of how are you? It is not a phrase that German speakers would use in the context of asking how are you? but rather how did you..? Wie bist Du dort angekommen? / wie bist Du hier angekommen? - How did you get there/here?

How are you is wie geht's dir in German. You can answer it by saying: Gut, danke. (Fine, thanks.) If you are not feeling well, you can also say: Leider nicht so gut. (Not so good.) It's common in Germany to give an honest answer.
