## Homework Statement

Find the parametric equations for the line which passes through the point (3,5,7)

and parallel to the vector <2,6,8>. Is the line perpendicular to the plane 5x + 6y +7z = 10?

## Homework Equations

line equation, r = Ro + tV

## The Attempt at a Solution

line equation, r = Ro + tV

-------------> = <3,5,7> + t<2,6,8>

hence, x = 3 + 2t ; y = 5 + 6t ; z = 7 + 8t

the problem is.. how am i going to prove that the line perpendicular

to the plane 5x + 6y +7z = 10 or not..?
