Answer:
Use the usted/ella/el form for the verb vivir which means to live, and that would be vive ( also the formal way to say you live). This is what you would use for some of the statements. You could also use vivemos for we live, viveis ( the i has a tilde) for you all live, viven for they live, and vives for you live.
