    1. The problem statement, all variables and given/known data
    Find the equation of the line, p, that is perpendicular to r=(1,1,1)t + (3,5,2) and passes through (3,3,1)

    2. Relevant equations

    dot product =0

    3. The attempt at a solution
    I understand that the direction vector r and p, when dot producted must =0
    but ive forgotten what to do from here

    Apparently, you've seen how to solve this type of problem before since you said you forgot what to do. Have you looked in your textbook and notes for an example you can follow? You need to use the resources you already have to try figure it out on your own before asking for help here.
