Exploring y=mx+b with Sliders

① This GeoGebra example demonstrates how the graph of a linear function y=mx+b changes as the slope m and y-intercept b are adjusted using interactive sliders. ② It covers core concepts of linear equations, including the geometric meaning of slope and intercept, and how parameter variations affect the line's steepness and vertical position. ③ The construction uses the Slope command to compute and display the slope, and creates objects m, b, a, and m_1 as sliders or auxiliary elements, allowing real-time updates of the equation and graph. ④ It is suitable for middle and high school students learning linear functions and introductory coordinate geometry, and serves as an effective tool for classroom demonstrations or self-directed exploration to build intuition about parameter-graph relationships.
