In this video we use GeoGebra (geogebra.org) to create a set of parametric equations that move a point from a starting location to an ending location along a straight line segment.

We use curve, create a slider, put a point on a curve, control the motion of the point, and make a new curve that will follow the start and end points as they are moved around. All fun skills to have and help you get closer to animating your own graphs and designs.
