What's My Number Line Rule #5?

This GeoGebra interactive example is designed to accompany the Exeter Math 1 curriculum, focusing on visualizing and solving 'What's My Number Line Rule?' problems. It demonstrates how geometric points on a line represent numerical values and help deduce underlying arithmetic or statistical patterns. The core mathematical concepts involved include coordinate geometry, the real number line, linear relationships, spatial coordinates, and basic statistics, specifically the concept of mode. In terms of construction, the example utilizes the fundamental GeoGebra `Point` command to define and manipulate key objects A and B, establishing a visual coordinate framework on a straight line. This resource is highly suitable for middle school and high school students, math teachers, and educators seeking to bridge abstract algebraic rules with concrete, interactive geometric visualizations.
