If you're working in two dimensions, yes. If you're working in more dimensions, you need to make sure they're not skew; the easiest way to do that is to attempt to find your intersection.

Set the two equations equal to each other and solve for t, then plug t into both your equations to make sure it gives you the same point in each. If it does, you've found your intersection. If it doesn't, the lines are skew.And how would I find the point?
