Homework Statement


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)


Homework Equations



dot product =0

The Attempt at a Solution


I understand that the direction vector r and p, when dot producted must =0
but I've forgotten what to do from here

Compute the dot product and set it = 0.
 
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.
