Slope - Lesson 4.6

We started today by looking at something that you've done in the past: figuring out the slope of a given line.  We all remembered that if we have a graph, then it's easy to find the slope by counting the rise over the run: We then looked at the general case and came up with the following conjecture (I know you've covered this before - just make sure you remember how to do it!!): We then recalled what different types of sloped lines look like...you should be able to tell which of the line below have positive slope, negative slope, 0 slope, and an undefined slope. We then looked at the slopes of parallel and perpendicular lines...you should be able to confirm that these theorems hold true by using the coordinates given:  We ended by going over the following example...can you answer all the questions posed?  If not, make sure to come to extra help!!
