y = mx + c Explained | Equation of a Straight Line | GCSE Maths

Learn how to use y = mx + c to understand and graph the equation of a straight line. In this GCSE Maths lesson, we explain what m and c mean, identify the gradient and y-intercept, rearrange equations into y = mx + c form, plot straight-line graphs, understand what happens when c = 0, and find the equation of a straight line from a graph. In this lesson: • What y = mx + c means • m = gradient • c = y-intercept • Identifying m and c from an equation • Rearranging equations into y = mx + c • Plotting a straight-line graph • Understanding when c = 0 • Finding the equation of a line from a graph • GCSE Maths quick challenge • Final recap CHAPTERS 0:00 Introduction 0:04 The Equation of a Straight Line 0:25 What does y = mx + c mean? 1:09 Read an equation instantly 2:37 Rearranging into y = mx + c 6:32 Plot y = 2x + 1 7:50 When c = 0 8:24 Find the equation from a graph 10:24 Quick Challenge 11:45 Final Recap 13:31 Keep Learning With Us Get Me Tutor Online Personalised 1-to-1 online tutoring 🌐 Website: getmetutor.online ▶ YouTube: @GetMeTutorOnline 📷 Instagram: @getmetutor.online 📘 Facebook: getmetutoronline 💼 LinkedIn: Get Me Tutor Online #GCSEMaths #StraightLineGraphs #MathsRevision
