Question

Determine the symmetric equations for the line through P(5, 6, 10) and parallel to the line with equation = (6, 1, 1) + t(−2, 1, 3).
Part b) Determine two other points on this line.

I've already figured out that the symmetric equations can either be x-5/-2=y-6/1=z-10/3 Or 5-x/2=y-6/1=z-10/3, but I'm having trouble remembering what to do for part b
