Basic Scatter Plot

This example demonstrates how to create a scatter plot and fit a line to the data. Key math concepts include scatter plots, vectors, indefinite integrals, step functions, trapezoids, and special points. The construction uses the GeoGebra command FitLineY and involves objects such as A, A1_1, B1_1, A1, B1, A2, B2, A3, B3, A4, B4, A5, B5, A6, B6, A7, B7, A8, B8, A9, B9, A10, B10, A11, B11, A12, B12, A13, B13, A14, B14, A15, B15, A16, B16, A17, B17, A18, B18, A19. It is suitable for middle school and above students learning data visualization and linear regression.
