Dynamic Slope Grapher is an interactive 3D model that helps you understand slopes on a graph. It includes a curve with two points you can slide along the line. When the points are close together, it shows the slope at that exact spot, called the tangent slope. When the points are farther apart, it shows the average slope between them, known as the secant slope. This tool makes it easy to see how slopes change and helps bring math concepts to life in a simple, hands-on way.
