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!
probably the same as Paralove is recommending
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.
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:
