Find parametric equations for the line that passes through the points p(1, 2, −1) and q(−1, 0, 1).

Brook states that the distance on the line is 4 units. caleb states that the whole line does not have a distance because it continues on forever. vivian states that the line is 6 units long. which distance did brook measure? which distance did vivian measure?
