## Homework Statement

find equation of plane P that is perpendicular to line L which passes through the point (-2,-2,3)

## Homework Equations

...

## The Attempt at a Solution

[/B]line L passes through the points (1,2,1) and (0,0,-3) I have worked out the parametric equations of line L to be

x=1-t

y=2-2t

z=1-4t

i know that if dot product of two vectors = 0 then they are perpendicular if that helps. im stuck on how to piece this question together.

any help would be greatly appreciated
