I 1st year linear algebra question

  1. Jan 19, 2017 #1
    given P(-1,1,2), Q(-3,0,4), R(3,2,1), find an equation of the line through P that is parallel to the line through Q and R.

    All the words after the given three points really confuse me and I just need some help on where to start to tackle this problem.
