GCSE Maths - How to Find the Equation of a Straight Line (y = mx + c) #68

The video tutorial explains how to derive the equation of a line from a graph using the formula Y = MX + C, where M is the gradient and C is the Y intercept. It demonstrates the process with examples, showing how to calculate the gradient by finding the change in Y divided by the change in X, and how to identify the Y intercept. The tutorial provides step-by-step guidance on applying these concepts to find the equation of a line from given points on a graph.
