Ratios and Lengths by David Wees

This example demonstrates how to dynamically adjust the ratio between two numbers using a slider and visualize the resulting ratio as a line segment. Core math concepts include ratios, line lengths, and function representation. It uses GeoGebra commands like Segment, Line, and Intersect to construct the visual model. Suitable for middle school and above to understand the relationship between ratios, function graphs, and geometric representations, as well as for statistical correlation visualization.
