If an equation can be rearranged into the form \(y = mx + c\), then its graph will be a straight line. In the above: \(x + y = 3\) can be rearranged as \(y = 3 - x\) (which can be re-written as \(y = ...

The equation of a straight line can be worked out using coordinates and the gradient, and vice versa. Practice determining the equation of a straight line ahead of your National 5 Maths exam with this ...

I was not a big fan of math in school. It’s not that I could not do it; it just never excited me. I did just enough to pass math class and get on to something else. I never envisioned myself in any ...
