This example demonstrates how to calculate y-coordinates corresponding to x-values from a linear equation and observe the plotting of points to form the graph. Core math concepts include linear functions, coordinate geometry, and equation solving. GeoGebra commands and objects used in construction are If, Segment, Textfield, Polygon, Point, Vector, Translate, Rotate. Suitable for middle school and above students to learn about the properties of linear function graphs.
