Unit #4.Lesson #1.Proportional Relationships

In this lesson we look at the simplest of all linear relationships, the proportionality of two variables. This should be a review topic for students at this level and the linear graphs passing through the origin should be familiar to kids. The first exercise is an example of a discrete proportional relationships, which I kind of botch in the Answer Key. But, I still kind of think that a connected graph, although not correct mathematically, would very likely be represented this way in almost any typical graphical representation.

I’m going to stop posting the link to the lesson and video given they are now easily accessible on our main page. I will however link to the Unit page:
