1. Real-life scenario

2. Live graph
Drag the green START point or red END point along the line. Release either point to freeze both coordinates, rise, and run. Drag again to explore a new point. Drag the blue point to change b, or drag the orange point to change m. The green and red points move along the line without changing its equation or slope.
3. Rise and run
Run is the horizontal change (right). Rise is the vertical change (up or down). Rise = slope × run. Drag either endpoint on the graph and release to freeze the triangle. You can also adjust the run slider to explore equivalent slope triangles. The slope stays constant when only run changes.
