I have one book that school gave us at the start of GCSEs but I'm not finding it helpful. Any suggestions/which one you guys use? appreciate it thanks!

I used one that I think was an edexcel one. It was light blue. There was a revision guide and a workbook... It really helped! Has all 3 units

6. A straight line, L, passes through the point with coordinates (4, 7) and is perpendicular to the
line with equation y = 2x + 3.
Find an equation of the straight line L.

No. It's just easier to explain which topics I hate because they're all in that unit 3, I'm glad I'm not doing modular because I'd get a big fat U on that exam.

Remember that if your line is perpendicular the gradient will be the negative reciprocal of the original line, in this case your gradient is - 0.5. Now substitute your x value ( 4 ) and y value ( 7 ) into y = mx + c to find the value of c ( the y-intercept )
So, 7 = - 0.5 x 4 + c, giving c the value 9. Your new equation is now y - 0.5 x + 9. Hope this helps from Mr. G

I've found that CGP books are generally very helpful when it comes to revision: "cgp edexcel maths gcse" try:
