How to Graph a Linear Function
In the next example questions and maths activities I will explain to you all you need to know about graphing linear functions to pass your IGCSE GCSE Maths exam. A linear function is a function where the highest power of x is one. f(x) = 2x - 7 for instance is an example of a linear function for the highest power of x is one. When you graph a linear function you always get a line. Look at the picture on the side and the amount of lines you see in it. They can all be represented by a linear function. The line starting at the sun and going towards the text could be f(x) = -0.5x + 2. Check the next video in which I explain to you step by step how to graph and draw linear functions.
