Finding an equation of a line

Chapters

Introduction

Description

This video looks at finding equations of straight lines given certain information. I look at how to find the equation when given the gradient and intercept, two points, and a gradient and one point. There is a practical example at the end which shows how the questions might be structured around the theory.
