This is how to use graphs to solve equations in your GCSE & IGCSE exams for 2024 and 2025!

📚 Improve your grades 2x faster & get started for FREE with solution videos, clear revision notes, past papers, typical exam questions, fully explained model answers and more!

In this maths revision video, Save My Exams maths tutors are explaining the relationship between graphs and equations using worked examples and answers based on past papers on GCSE & IGCSE maths exams. In this explainer video, designed by GCSE & IGCSE maths examiners, you'll learn how the x and y axes work in representing solutions, allowing you to read the solutions directly from the graph. This is crucial if you want to tackle your GCSE & IGCSE maths exams and get top marks!

In This GCSE & IGCSE Maths Revision video, You'll Learn:

How to read solutions from the x-axis and dentify the x-coordinates where the graph cuts the x-axis, as these points represent the solutions to the equation
Solve equations using graphs following our step-by-step approach to solving equations by visually identifying where the graph crosses the x-axis
Handle equations not in y = f(x) format: Rearrange the equation to match the format of the given graph, allowing you to apply the graphing technique
Identify intersection points: Find the points where the graph and the newly drawn line meet, as these points hold the key to solving the equation

After This Video, You’ll be able to:

Solve equations visually using graphs using our techniques to identify solutions to equations by interpreting their graphical representations.
Read solutions from the x-axis accurately and ranslate the visual information on the graph into numerical solutions to the equation
Handle equations presented differently so you can adapt your approach to solve equations even when they are not explicitly given in the standard y = f(x) format
Identify intersection points with precision so you can find the answer to the equation!

By watching our easy guide to graphing techniques for solving equations, you'll be better equipped for tackling various algebra problems encountered in your GCSE & IGCSE Maths exams.

Learn how to master graphing equations with Save My Exams and make sure you get top marks in your GCSE & IGCSE Maths exams!
