I was watching a football game a few days ago, and to prepare for it, we decided to pick up some snacks. As the game progressed, I found myself eating a lot of chips, but at halftime, there was one snack that remained unopened, a snack I had been thinking about all night, a snack that I couldn’t seem to locate until that moment – Recee’s Pieces. We purchased a pretty large sized bag that I thought would last a while. So at the end of halftime, when the bag was almost empty, someone made sure to warn me that at the rate I’m eating these things I’d be sure to be sick the next day.

Just to give you some insight into my how my mind works, the fact that she used the term “rate” took me back to classes of Algebra 1 where we were first learning about linear equations, slopes, y-intercepts, point slope form, slope intercept form, and so on. The more I thought about it, the more I thought this would be a good script to add to this site as it would probably provide help to many students who are currently enrolled in those classes as well as a remembrance to adults who took those classes years ago and wish to recall the concepts.

So I have added a script which helps go over the slope formula. It randomly generates two points and asks users to select which of a set of choices is the slope of those two numbers. In case you forget, there is a button where you can be given the slope as well.
