This is the first video in a new series looking at linear relationships (and we don't mean those types of relationships!!) The General Maths Units 1 and 2 course is awesome and has some really great real world Mathematics in it. This video looks at how to draw a straight line graph when given an equation. Initially we look at plotting the graph using a table of values. I look at a number of examples and explain how to understand the algebra to ensure that your graphs are as straight as an arrow. I do all I can to ensure that you fully understand the content.

This is the next video in the Linear part of the General Maths Units 1 and 2 course. Having spent some time looking at how to plot straight lines in the previous video, I now look at how we can find the gradient of a straight line using the rise over run formula as well as another more interesting (and definitely more funky) formula. We look at positive, negative, zero and undefined gradients and what they mean with lots of worked examples all explained in my own unique way!

This is the next video in the series where we look to find use the intercept-slope form of an equation. I take the time to look at what this equation looks like and the ways Barry can use to try and trick us. I show lots of examples of how to write it, change it and express it to ensure that you smash this part of the General Maths Units 1 and 2 course. The video uses the Cambridge General Maths examples (thanks Cambridge!) which are second to none and show you all your need to know.

This is the next video in the series which looks at linear relations for the General Maths Units 1 and 2 course. Finding the equation of a straight line graph from its intercept and slope is a really interesting part of the course and I love this stuff! I take a look at how to find the equation of the line by reading off the intercept on the y-axis and then draw triangles to find the gradient. Substituting this into the equation and we're done! There are a number of worked examples which are all explained in my no nonsense, easy to understand way!

This video is another in the General Maths Units 1 and 2 course looking at how to find the equation of a straight line using only two coordinates (or points!). Building on past content, I take a look at how you can use the equation y=mx+c alongside two coordinates on a graph to find the equation of the line. I show you two different ways of doing this (the hard way and the easy way) with a number of worked examples all explained in my own unique way!

Life is so much easier with a calculator isn't it! Well, it is with the General Maths Units 1 and 2 course where we can use the CAS to help us find the equation of a straight line using only two coordinates (or points!). This video has been created to teach you how to find the equation of a straight line graph using two points on the graph. I explain the theory behind what it is you're trying to do and then use some practical examples to show you how easy it is! Why can't all questions and topics be like this.
