Slope Formula from a Table

This example demonstrates how to calculate the slope of a line using data from a table. Core math concepts include the slope formula, coordinate geometry, and data analysis. GeoGebra commands and objects like Textfield, Line, If, and objects such as B1, A1, A2 are used for inputting data, drawing lines, and conditional logic. Suitable for middle school students and above learning coordinate geometry and data processing, or for educational demonstrations.
