Hello carmen, to handle this topic you must first familarise yourself with all the important fomulars for this topic! I have boxed up the fomulars in pink for each question type and simplified the solutions for better understanding. Hope they help! For question 2 you have to draw out the dciagram according to the coordinates using the X and Y axis. Try attempting ques 2 on your own first with the fomulars. Cheers! (:
