Pre-Calculus question pissing the shiz out of me.

(1/1)

........:
Find an equation for the family of linear functions such that f(2)=1 and sketch several members of the family?

We know that when x=2 y=1 so this must mean that all lines must pass through (2,1). How could i make a equation for this?

and this question ii) What do all members of the family of linear functions f(x)=1+m(x+3) have in common?
