I don't think that's right. I'm going to ask the teacher.
Whats the formula to solve number 7?
I think its y=mb+x
What formula do we use to do number 7?
I'm glad I asked the teacher! I can always trust her!
The female student asks her friend how to solve number 7 because she is having trouble with it. The male student answers her but she is not entirely sure that he is correct. To double check, she goes and asks the teacher.
The female student goes and asks the teacher for the formula to use for number 7. The teacher then proceeds to give her the formula, which is different from the one given from her friend. She trust the teacher because she is a reliable source of knowledge.
The student then goes back to her desk knowing how to solve number 7 due to her teachers knowledge.
