Description

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!
