these are meaningless ploys and toys of the CGP books

I do not know whether you are at GCSE or AS level

This is the GSCE version

x -3y -3 =0

rearrange in the form y = mx + c

x - 3 = 3y

divide by 3

y = (1/3) x - 1

any perpendicular line will have as gradient the negative reciprocal of 1/3

in this case -3

Che CGP actual textbooks for A level are of decent quality.
(I believe they are written by a team of mathematicians)

Their Revision Guides for GCSE and A level are absolutely dreadful.

Ah I've no experience with the textbooks - We tend to use the ones written by our exam board. Which exam board does CGP follow in its textbooks? Does it cater to all?

I think their books are multi-board but they are really written for EDEXCEL
I saw a copy of these only very recently.

Ah I see. We used their textbook for GCSE ICT (Edexcel). It was terrible. We do Edexcel for maths but use the ones written by the Pearson

The Pearson books are good in my opinion except the C1 to C4.

Hmm really? Interesting. I actually did best in Year 12 in C1-3, and did considerably worse in M1/S1 (All learnt with Pearson textbooks). I thought they were quite good because, through examples, they derived most expressions (especially in C3/C4) that ended up in the formula book.
