Graphing a Vertical Line Segment without Parametric Equations

This example demonstrates how to graph a vertical line segment without using parametric equations. By changing the numerical values, you can easily adjust the lower and upper bounds of the segment. The core mathematical concepts involve linear equations and analytical geometry. Key construction steps include using the Segment command to draw the segment, the Midpoint command to find the midpoint, and objects such as UB, LB, X, A, B, f, C, and text1. It is suitable for high school students learning analytical geometry and function graphing.
