Hey guys,

i am stuck with a couple of questions and don't no how to get started! if anyone can help that'd be muchly appreciated.
a) find a vector equation and parametric equations for teh line through the point (6, 0, -6) and parallel to the vector 10i - 8j + 6k.

b) find a vector equation and parametric equations for the line through the origin and parallel to the line x= 10t, y=10 - 9t, z=7 + 10t and

c) find parametric equations for the line through (7, 2, 0) that is perpendicular to the plane 2x - y + z = 1.

Thanks heaps if anyone can help get me started!!
Regards
Alice
 
These are standard example problems in any good vector/analytical geometry book. Notice all three problems are very similar.

Did you check those problems in your text-book?
