Explore how a and b affect the linear graph

This example demonstrates how changing the parameters a and b affects the graph of the linear function y = ax + b. It involves core math concepts like linear functions, slope, y-intercept, and function graph transformations. Constructed using GeoGebra commands/objects: a, b, c, text2, text1, text3, d. Suitable for middle school and above students learning about function graph properties and parameter effects.
