The graphs and relations module is actually one of the easiest modules to learn, since the level of maths does not increase overly much from Year 7.

I see you're having problems with Linear Models and Break-Even Analysis (which is basically another type of Linear Model). Linear models do have the tendency to be quite confusing, so make sure you're able to take out the key information. I tend to write all the relevant values down and try to treat the question as a normal linear graph. It also helps to read the question a few times as well and always check your answers on the calculator.

If you're stuck with any particular question, feel free to ask it on the forums. Most of the community here are very smart and helpful.

Good luck!

It is a slight extension to what I learnt last year ... So, I didnt really have trouble with it but i would have if i didnt have a firm grip on linear from year 10 ... Also doing methods ch 1+2 (essential) helped... Whenever i am stuck on a concept i look at the previous years book and that usually helps and i suggest you do the same
I beg to differ stick, while nothing is essentially 'difficult' in further, linear relations and trig and geo are considered to be the hardest two but i agree that its just a build-up of yr7-10 maths
All the best molllz

Well it might not be the 'easiest' module, but it's a module that's basically taught since Year 7, so most people tend to do alright in it.
