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.
