How to solve straight line graphs
WebJun 29, 2024 · To avoid confusion, keep in mind to always have a positive y. 2. Determine if the gradient or m is negative or not. So there are two sides to choose from: y=mx+c or y=-mx+c. If the line goes from top right to bottom left, m is positive. But if the line goes from top left to bottom right, m is negative. 3. Webthe short answer is; to find a common factor from the function ax^2+bx+c - find two numbers d & e that multiply equal a times c; -- d*e=a*c that add up to b; -- d+e=b In the video that are -6 & -1 as they multiply to get 3*2 and add up to -7 1 comment ( 3 votes) Upvote Downvote Flag more Macia 2 years ago At 2:30 , why does he solve for y?
