Hi, my name is Stefan. Today, I'm going to be speaking on linear functions in math projects. A good project to do is a jogging project. America is suffering from an obesity problem so they are saying we need to get out and jog. A project I do is I measure my rate and how long it takes me to run a certain distance, Distance D, usually I do about 600 meters and this axis is the time and day 1 it will look something like this and then on day 2, it will look something like this and then on day 3, now it will show you that I'm getting faster and faster, it's taking me fewer and fewer hours to run the given distance and these lines, these are linear functions because you run at a constant pace. So there's a great linear math function project for you to do, gets you healthy and gets you to learn math.
