This is another video in the Year 11 General Maths (VCE Units 1 and 2) course looking at algebra and linear. Straight line graphs are going to be really important in Year 12 and so I take a look at what a straight line is and how we can draw straight lines by plotting points. I look at the important parts of a straight line such as the y-axis intercept and the slope as well as the concepts behind positive gradients, negative gradients, parallel gradients and how we might be able to find the measure of the slope. There are a number of worked examples which are all well explained. There is even more humour!
