This video is the first in a new series on Linear Relationships at a Year 9 level. Introduction to Linear Relationships does exactly what it says on the tin. I take a look at all the work you are going to need to be able to access the rest of the content. Whilst the video is a little long(!) I do take time to explain everything you are going to need. There is humour and lots of worked examples so you will become a guru in this topic.
