Lets draw a figure representing the problem
my comp

  1. A horizontal line on a V-T graph represents a #ul"constant"# velocity.
    Notice that in the horizontal line shown in blue, velocity does not change with time.

We know that the area bound by the line and the axes of a velocity-time V-T graph is equal to the displacement of the moving object during that particular time. Again see the blue line.
2. As such: A horizontal line anywhere above the time axis means motion in the #ul"velocity's"# direction

  1. A horizontal line on the time axis means no motion.
    See the red line. Area under the V-T time graph is #0#. Also notice that for this line #"V"=0#.
