I'm not learning but in this day and age, we don't need to learn it. By inspecting the parametric equations of both lines, we see that the direction vectors of the two lines are not scalar multiples of each other, so the lines are not parallel. Note that this definition agrees with the usual notion of a line in two dimensions and so this is consistent with earlier concepts.
