Students interpret the meaning of the point of intersection of two graphs and use analytic tools to find its coordinates.
The intersection point of the graphs of two equations is an ordered pair that is a solution to BOTH equations. In the context of a distance (or elevation) story, this point represents the fact that both distances (or elevations) are equal at the given time.
Graphing stories with quantities that change at a constant rate can be represented using piece-wise linear equations.
