Point-Slope Form Demonstration

This example demonstrates the point-slope form equation in the Cartesian coordinate system, including its graph and variation patterns. Core mathematical concepts involve point-slope form, slope, linear equations, and coordinate geometry. Construction highlights include using the Slope command to calculate the slope and objects like a, b, P, x₁, y₁, m, eq1, text2, text3, m₁, text4, text5, text1 to build and display the equation and graph. Suitable for high school students learning about the geometric meaning of linear equations and the impact of parameter changes.
