Rest of 9.1

We wrapped up section 9.1 today in class by looking at a couple of examples.  Specifically we looked at each of the 4 cases.

1 soloution - 1 point of intersection
infinite solutions - lines are coincident (on top of one another, or the same line)
no solutions (2 seperate cases) either lines are parallel and non-coincident OR lines are skewed, that is not parallel but still not intersecting.

I will assign offical homework for this section in class on Thursday...
