Graphical Representation 
The Law of Change for the One-Dimensional Motion with Constant Velocity model can be expressed:
which is remeniscent of the equation for the slope of a line. In fact, if we plot a position versus time graph, then the equation above becomes exactly the equation for the slope of the graph. Since we know that v is constant, the slope is constant and the graph will be a line.
A Velocity for Words (Put the motion described by these graphs into words.)
