Answer:
Yo soy alto
tu eres alta
usted es alto
el es alto
ella es alta
nosotros somos altos
nosotras somos altas
ustedes son altos
ellos son altos
ellas son altas
The first part of this assignment tells you what goes on in the first line.
for the seccond line it stays as alto for I,you,he, and usted, just add a s for the plural conjugations and for the femenine like she is alta and add a s for like nosotras which is we but like for a group of females.
Does that make sense? if not just let me know ill try to explain it further.
