This example demonstrates how to find the slope of a line given two points on it. Key math concepts include linear equations and slope. The construction uses GeoGebra commands such as Sequence, RandomElement, Union, FractionText, and Textfield. Suitable for middle school and above students to practice linear equations and slope.
