Linear Functions: An Introduction

This video introduces linear functions. The presenter, Sharpie, outlines the different forms of linear functions: tables, graphs and equations. The students explore the concept of the y-intercept and learn how to determine the slope of a line given any two points on the line. As students plot linear graphs from linear equations, they discover with the gradient and y-intercept they can both sketch the linear graph and determine the linear equation for a line. There are opportunities for students to practice the concepts throughout the video.
