math,help

this other one how can i actually prove it if this is the equation to use.

the problem states:

Prove that if a line has slope ma nd y-intercept b, then an equation of th eline is y=mx+b. then it says (Hint: use the point-slope equation theorem)

I've looked at it but i understand it but i don't know what to answer for this problem.
