GCSE Maths - Finding the Equation of a Straight Line From 2 Sets of Coordinates

⭐️ https://www.cognito.org/ ⭐️ *** WHAT'S COVERED *** 1. Finding the equation of a straight line when given two coordinates. 2. How to use the three-step method: * Step 1: Calculate the gradient (m) using the formula. * Step 2: Substitute the gradient (m) and one of the coordinates to find the y-intercept (c). * Step 3: Write the final equation by substituting the calculated values into y = mx + c. 3. Two worked examples demonstrating the method. *** EXAM BOARD INFO *** This video is suitable for maths courses around the world.
