Graphical Solution of Systems of Linear Equations

This GeoGebra example demonstrates the geometric interpretation of a system of two linear equations: the intersection point of two lines in the plane represents the solution. Core mathematical concepts include linear equations, slope and intercept, intersection of lines, and solution sets of systems. The construction uses the Intersect command on two lines f_1 (defined by slope m_1 and intercept b_1) and g (defined by slope m_2 and intercept b_2), producing the solution point h. Suitable for middle and high school students learning algebra and coordinate geometry, it helps visualize unique, no, or infinite solutions, and is ideal for classroom demonstrations or student exploration of how changing parameters affects the solution.
