Translation for spanish i class? *picture included* not sure what to do with boot verbs

For the boot words you would change the letters to e-ie or e-i. So basically for nosotros and vosotros which are not part of the boot you would not change the letters and it would be the same in the middle of the word but it have a different ending. So like number 2 it's nosotros so it would be nosotros servimos.

1. a. sí, conocen a tu amiga maria2. b. sabe
