## Homework Statement

Is the line through (-2, 4, 0) and (1, 1, 1) perpendicular to the line through (2, 3, 4) and (3, -1, -8)?

## Homework Equations

R = R

_{0}+ tV (for each line)

## The Attempt at a Solution

If the lines are parallel, then the V for the two equations will be proportional to each other. How are the two V's related if they are perpendicular?
