Graphing Two-Step Equations

① This example demonstrates how to visualize a two-step linear equation (e.g., ax + b = c) by graphing its corresponding straight line, linking algebraic solving to geometric representation. ② Core mathematical concepts include linear equations, slope and intercept, coordinate plane graphing, and interpreting the solution as the intersection point with the x-axis or another line. ③ Construction details: The GeoGebra commands use the Line tool to create lines a and b, with points A and B defining key positions, while button1 and text1/text2 provide interactive step-by-step feedback, showing how each algebraic operation (addition/subtraction, multiplication/division) corresponds to a geometric transformation such as shifting or scaling the line. ④ Suitable for middle school students learning the connection between equations and graphs, and for teachers demonstrating the visual meaning of solving two-step equations in a dynamic classroom setting.
