What is the Gradient of a line and how to calculate the Gradient?

It is important to have a firm understanding of what the gradient of a line is. You will get questions about gradient on your IGCSE GCSE maths exam. Why are some gradients positive and others negative? What is going on when the gradient of a line is a fraction? Only if you understand the answers to these questions you will be able to do future maths questions comfortably and confidently. Study therefore the following two videos first in which I explain to you in detail what the gradient of a line is. Then you can move on to the next videos in which you will learn how to calculate gradients. The second video (Part 2) already shows you the relationship between the gradient of a line and its equation. Have fun examining the following maths activities!

Study the following video too during your maths revision in which I explain to you the relationship between the gradient of a line and the equation of a line. A very important video to check if you want to pass your maths exam!

I hope these maths videos were useful and that you understand now what the gradient of a line is. Once you understand and can picture the difference of a line with a gradient of 2 compared to a line with a gradient of -0.5, it is time to start calculating gradients. Have a look therefore at the next maths activities which will provide you with many maths example questions.

How to Calculate the Gradient when given two coordinates

Once we truly understand what the gradient of a line is, we can start calculating gradients. You will most likely have to do a similar thing on your IGCSE GCSE maths exam. The following maths videos will show you step by step what to do when you are given two points/coordinates and you are asked to calculate the gradient of the line going through these points. Make sure to let me know if you still don't understand how to calculate the gradient of a line and I will help you with your maths.

In the next video I will continue to explain how to calculate the gradient when you have two points. I will provide you with more example questions so you really understand how to calculate the gradient of a line.

It is your turn to do some work now when you have studied the previous two tutorial videos! Both videos below provide you with an example question so you can discover whether you understand how to calculate the gradient. Start the video, pause the video, solve the question yourself, play the remainder of the video and check your workings (and your workings are far more interesting than your answer!!)! Believe in yourself! Have fun!

Calculating the gradient when given a line

If you understand how to calculate the gradient when given two points, it is only a small step in to understanding how to calculate the gradient when given a line. Please realise that you are required to be able to CALCULATE the gradient. Naturally you can easily check your answer by looking at the graph.

Congratulations! You now understand all you need to know about what the gradient is and how to calculate the gradient to pass your maths exam!! Continue with your maths revision and follow the link below. Here I will explain to you how to construct the equation of a line using the gradient-intercept notation. Another important maths topic to understand!
