Intersection of Two Lines by Tony Jacobsen

This GeoGebra example allows users to input two linear equations via interactive input boxes. It then computes and displays their intersection point in exact fractional form. The core mathematical concepts include linear equations, coordinate geometry, and the algebraic solution of equation systems. Construction features the Intersect command to find the intersection point, Textfield and SurdText commands to display fractional results, and inputBox1 and inputBox2 for editable equation entry. Relevant objects include coefficients a and b, and the intersection coordinates xval and yval. The example is suitable for middle and high school mathematics, helping students visualize the geometric meaning of linear equations, understand the conditions for solutions of equation systems, and engage in classroom demonstrations or independent exploration.
