Exploring Linear Equations and Graphs

Introduction

Have you ever wondered how we can represent real-world problems using math? Linear equations are powerful tools that help us describe relationships between two variables. In this WebQuest, you will explore how to write, solve, and graph linear equations, and see how they apply to everyday situations like budgeting, distance, and speed.

Task

Your task is to become a math detective! You will investigate the components of linear equations, learn how to graph them, and solve problems using these equations. At the end, you will create a real-life word problem involving a linear equation, solve it, and present your solution with a graph.

Process
  1. Review the basics of linear equations, including slope and y-intercept, using the provided resources.
  2. Watch tutorial videos on how to graph linear equations on the coordinate plane.
  3. Practice solving linear equations with step-by-step examples.
  4. Explore real-life examples where linear equations are used (e.g., calculating costs, distances).
  5. Create your own word problem involving a linear equation.
  6. Solve your problem and graph the equation using graphing tools like Desmos or GeoGebra.
  7. Prepare a short presentation explaining your problem, solution, and graph.
