Feedback on parametric-form

[QBobWatson]

That's something that we cover in parametric vector form, no? It's useful to realize later on that they've already written down a vector equation as a system of equations.

Ok. It's just that in this section, there is the example at the top and then much later in the implicit vs parametric section you all of a sudden see (1-5z,-1-2z,z). It would be good to recall the parametric solution before putting this. Otherwise, it comes out of nowhere. My original comment above is related to this form here. I was suggested that we explicitly say how to get this form: put the free variables in their spots, and use the equations to figure out what to put in the other spots. I haven't thought of a great way to say this.

I see what you mean. I made an attempt at an edit -- what do you think? (Just close the issue if it's ok.)
