What do you think of when you hear the term, slope? Do you think of a skier, skiing down a large mountain?
Or, maybe you think of the sliding board at the playground.
Whatever you are thinking, it's probably something that's on an incline! When we study slope in Algebra we are going to study the incline and other characteristics of a line on a graph.
Slope is a very important concept to understand in Algebra. Therefore, I've created three different lessons to help you gain a full understanding.
Start here from the beginning, or move onto the concept of slope that you need help with!
Slope is used very often in Mathematics. It can be used to actually find how steep a particular line is, or it can be used to show how much something has changed over time. We calculate slope by using the following definition.
In Algebra, slope is defined as the rise over the run. This is written as a fraction like this:
There are two examples below. You can watch how I calculate the slope in the video lesson, or you can skip the video and check out examples 1 and 2 below.
Let's take a look at another example where the slope is a fraction.
Just remember that slope is a fraction: rise/run. Calculate your rise and then your run!
If your rise is downhill it is negative. If your run is to the left it is also negative!
You can choose any two points on the line to calculate your slope! The slope is constant throughout the whole line.

"I'd like to start off by relaying my sincerest gratitude for your dedication in teaching algebra. Your methodology is by far the simplest to follow, primarily because you take the time to include the small steps in between that most other teachers leave out.
It helps to know why you are doing something. I am 45 and heading to college to get my BS in Business. I need to brush up, hence the visit to your site. Great Job!"

"I stumbled onto your site after I found out that I needed to use some fundamental algebra for an assignment. Turns out I had forgotten some things and your great site helped me remember them like "that" (snap of fingers). The organization of the site let me find exactly what I was looking for so easily. Kudos to you for maintaining such a great resource for students of all ages!"

"I just wanted to write and basically thank you for making such a wonderful website! I'm 20 years old and about to take a basic placement test for college. I wanted to brush up on my Algebra skills and I stumbled upon your site. I'm amazed at how simple you make it and how fast I'm remembering Algebra! I don't remember getting most of the answers right when I had an actual teacher in front of me teaching this. Thanks a lot!"

"I am a pensioner living in South Africa. I stumbled on your website, the best thing that could ever happen to me! Your course in Algebra has helped me a lot to better understand the different concepts. Thank you very much for sharing your skills for teaching math to even people like me. Please do not stop, as I am sure that your teachings have helped thousands of people like me all over the world."

This is an amazing program. In one weekend I used it to teach my Grade 9 daughter most of the introductory topics in Linear Relations. I took her up to Rate of Change and now she can do her homework by herself.
