In this video we'll talk about finding the slope (gradient) of straight line. We'll also talk about how the formula was 'created'. Check out my YouTube channel "Like a Math Class" https://www.youtube.com/channel/UChykduc4dEGbl9-l8c9UvUw What's unique about the slopes of parallel and perpendicular lines? https://youtu.be/mjD3fsQlHTQ Chapters: 0:00 - Introduction 0:16 - The many representations of slope 1:57 - Counting 4:56 - Constructing the slope formula 7:14 - Wrapping it up #IBMath #MathHelp #BackgroundKnowledge #LinearEquations Legal Disclaimer: This video/channel is not affiliated with or sponsored by the International Baccalaureate.
