Interactive Linear Equation & Inequality Solver with Draggable Points

This example demonstrates how to dynamically solve linear inequalities by dragging two movable points A and B. The core mathematical concepts include solutions to linear equations and solution sets of linear inequalities (greater than, less than, or between two values). Construction details: Uses Point command to create draggable points A and B, Text command combined with x(A) and x(B) coordinates to display equation solutions and inequality solution sets in real-time, and Polynomial command for verification. Suitable for middle school mathematics teaching on linear equation solving and inequality solution sets.
