Solving Linear Systems by Graphing: Dynamic Intersection Demo

① This example demonstrates how to solve a system of linear equations by graphing two lines and observing their intersection point, which represents the solution. ② Core math concepts include linear functions, slope-intercept form, systems of equations, and the geometric interpretation of unique, no, or infinite solutions. ③ Construction highlights: uses GeoGebra's Intersect command to find the intersection, FractionText to display coordinates as fractions, Textfield and InputBox for editable equation inputs, button1 to trigger updates, Point objects to mark the solution, and text objects for labels. ④ Suitable for middle school to high school students learning linear equations and systems, as well as teachers for interactive classroom demonstrations, bridging algebraic and geometric reasoning.
