Gradient and Intercept for Straight Lines

This example demonstrates how changing the gradient and y-intercept affects the graph of a straight line. It also shows how the gradient is calculated from two points. The core math concepts involved include the equation of a line, gradient, and intercept. GeoGebra commands and objects like Point, Polygon, Angle, FractionText, and LaTeX are used to create points and polygons, measure angles, display fraction text, and render mathematical formulas during construction. Suitable for high school students learning analytical geometry and understanding the meaning of line equations and their parameters.
