It shows the speed of an object in a direction towards or away from the reference point. This is not the speed of the object because any motion in a transverse direction is ignored. For example, even if a racing car is going at top speed around the reference point on a circular track, the distance v time graph will be a horizontal line. The slope will be zero.

the slope show the velocity of the object which show its direction and magnitude.
The slope of the line would decrease.
There are many things the graph does not show. It does not show my shoe size, for example.
if the speed is zero then the distance versus time line will be horizontal
a vertical one
