Finding a parametric equation to a line

How would you find a parametric equation for a line passing through a point and perpendicular to a line passing through two other points?

Here is an example given to me, "Find parametric equations of the line passing through (3, -1, 3) and perpendicular to the line passing through (3, -2, 4) and (0, 3, 5)."

I have been reading around and I've only found information about how to find an equation to a plane but not a line. How would you approach this question? Any help would be appreciated! Thanks!
