Help with these two? Thank in advance! :)

How do i answer this? ¿dónde estás? ¿dónde está tu amigo/a?

Ineed someone who has either taken the unidad 9 prueba_gramática quiz, or at the very least, knows the passive voice in spanish to answer this question. completa la oración con la voz pasiva con se. the cake was eaten. la torta. there are no answer choices provided, you must simply fill in the blanks. 'se comieron' and 'venta de' are incorrect answers, so do not answer with either.
