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!
