If you are analyzing speed with respect to time, then you are decelerating.
The object is accelerating
An upward sloping straight line indicates that the object being studied is moving away from the origin and that the component of its velocity in the radial direction is a constant. A downward sloping line indicates it is moving towards the origin. However, neither line says anything about the transverse component of its motion.
The horizontal line represents that the acceleration is zero or constant speed and the line that slopes downward means that the object is slowing down and it is a negative acceleration.
This means your velocity is decreasing with time, or in other words, the object is slowing down.
That the object being studied is accelerating in the radial direction.
On a graph of acceleration vs. time, during deceleration the line is below zero. On a graph of speed vs. time, during deceleration the line has a negative slope (sloping downward from left to right).
Slowing down or decelerating
The object is accelerating
If you want the graph to show the acceleration of the ball against time, then the graph is a horizontal line. If you want the graph to show the velocity of the ball against time, then the graph is a straight line sloping downward. If you want the graph to show the height of the ball against time, then the graph is a parabola that opens downward.

That the object being studied is accelerating in the radial direction.
That means the speed (the slope of the position-time graph) is decreasing.
It means that either the distance is measured from the finish-line, or else the object is moving backwards, because the distance is shrinking as time goes on.
Because the expenses are greater than the income.
