Solving Systems of Equations by Graphing by Josh
Loading the math board and drawing, please wait…
This example demonstrates how to solve systems of linear equations by graphing two phone plan cost functions and finding their intersection points. Core math concepts include function graphs, linear equations, and intersection solving. GeoGebra commands used are Intersect and Polygon, with objects like m_1, b_1, m_2, b_2 representing different function parameters. Suitable for middle school math education to help students understand graphical methods for solving equations.
GeoGebra Commands & Parameters
Intersect(c, d) → APolygon((x(A), y(A) + 1), (x(A) + 10, y(A) + 1), (x(A) + 10, y(A) - 1), (x(A), y(A) - 1)) → underLabel, b, e, f, g
