How to identify the y-intercept (c) directly from the graph. 3. How to calculate the gradient (m) of a line shown on a graph. 4. Combining the gradient (m) and y-intercept (c) to write the full equation of the line. 5. Step-by-step worked examples demonstrating the method. *** EXAM BOARD INFO *** This video is suitable for maths courses around the world.
