Understanding y = mx + c for GCSE Maths (2026/27 Exams)

⭐️ Check out our website https://www.cognito.org/ ⭐️ *** WHAT'S COVERED *** 1. The standard form for equations of straight lines on graphs: y = mx + c. 2. Understanding the components of y = mx + c. * 'm' represents the gradient of the line. * 'c' represents the y-intercept. 3. Identifying the gradient and y-intercept directly from an equation in the form y = mx + c. 4. Sketching a straight line graph using its gradient and y-intercept. 5. How to rearrange linear equations that are not initially in the form y = mx + c. 6. Interpreting equations where the 'm' value is 1 or the 'c' value is 0. *** EXAM BOARD INFO *** This video is suitable for maths courses around the world.
