## Homework Statement

Determine the vector equation of the line that passes through the point P(1,3,5) and is perpendicular to the line r = (1,0,5) + t(-3,4,-6).

## Homework Equations

n1 dot n2 = 0

## The Attempt at a Solution

I know that the normal of the line I need to find and the normal of the line perpendicular to it have to dot to equal 0. The direction vectors of both lines also can dot to equal 0, too, right? I'm just confused on how to get the needed line and/or the normals of both lines.
