Lesson: Solving Linear Equations Using Function Graphs Mathematics

Start Practising

In this lesson, we will learn how to solve linear equations using function graphs and verify the answer algebraically.

Lesson Plan

Students will be able to

  • understand the relationship between solutions to linear equations and the graphs of the corresponding functions,
  • solve 𝑓(𝑥)=0 by examining where the graph of the linear function 𝑦=𝑓(𝑥) crosses the 𝑥-axis,
  • solve 𝑓(𝑥)=𝑐 by rearranging to get 𝑓(𝑥)=0 or by examining where the graph of the linear function 𝑦=𝑓(𝑥) crosses 𝑦=𝑐.
