Gizmo Warm-up The Distance-Time Graphs Gizmo shows a graph and a
runner on a track. You can control the motion of the runner
by manipulating the graph (drag the red dots).
Check that Number of points is 2, and that under Runner

The graph should look like the one shown to the right -
one point at (0,0) and the other point at (4.40).
