It would probably pay to give us a bit more info about what it is exactly that you need help with.
I can guess that your teacher is giving you a question such as:
¿Venden frutas y vegetales en el mercado?
And you understanding that it means - 'do they' sell veges, must answer with:
Sí, venden frutas ..... (yes 'they' sell fruit ...)
For this example nothing changes but if she was to ask 'Do you sell frutas ..? - 'Vende Ud frutas ...? you would need to answer with 'Yes, I sell fruit ....' Sí vendo frutas - changing the verb vender from 'vende' (Ud) to 'vendo' (yo).
I could however be way off and that's why a little more info would be gr8
