Math 20-3

Chapter 1 Slope and Rate of Change

Lesson 1.1 Rise over Run

Formula page

I expect that you will be able to use a formula page for this class,  but that will be determined by your teacher.

Your teacher may have a formula page they expect you to use.

Below is a link to the formula page I will use (at least for now!) when I’m doing questions for this class.

This may change, depending on feedback from your teacher.

I encourage you to download this page and print it so you have it handy when you are doing math.

Analyzing Slope  (optional)

The activity on pages 18 and 19 is to help with developing your ideas about slope.
I’ve included an alternate way to explore these ideas.

You can experiment with the demonstration below to see this visually.

Notes

Question 11,    A great question, but lots going on here that would take a long time to explain.
I am not sure if your teacher would expect you to do this, so I didn’t do a video for this one.
