Description
Linear relationships is a massive part of the Year 9, 10, 11 and 12 courses. Being able to draw graphs is going to be really important. This next video in the series will show you how to draw straight lines from intercepts. This really easy concept seems to confuse many students, so hopefully this video will help you. There are lots of worked examples and explained using plain English and lots of humour. Why not try something different.
