i find it easier to just write the lines as functions y(x) and from then it's smooth sailing
What I don't get is why did he change the t into u in the line L2
I think that you can think of the "trajectories" of the lines as having different speeds, so the "particles" of each line arrive at the point of intersection at different times, namely, t and u.
right but not in all cases they are trying to show you how to go about doing it parametrized way.
But there are parametric equations that one may not be able to break the parameters
i understand, but in this case it works
