Want this question answered?
Acceleration is how fast you get up to speed.
Motion at a constant speed - no acceleration or deceleration.
It tells you that the velocity of the body is not constant. There is acceleration or deceleration.
Since we cannot see the graph you're looking at, we can't answer the question.
The answer depends on what is plotted on the graph and what is happening with the acceleration then.
This depends on what the graph represents. If it is a graph of velocity on the vertical and time on the horizontal, then if acceleration is at a constant rate, the graph will be a straight line with positive slope (pointing 'up'). If acceleration stops, then the graph will be a horizontal line (zero acceleration or deceleration). If it is deceleration (negative acceleration), then the graph will have negative slope (pointing down).
Speed can be shown on a graph of position versus time, and acceleration can be shown on a graph of speed versus time.
I would hope that a graph of deceleration would be visible.
Acceleration is how fast you get up to speed.
A line graph. It shows both the acceleration and the deceleration.
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).
Yes. One shows speed and the other shows acceleration. The variables are usually plotted against time but that need not be the case. They could be plotted against displacement, for example.

deceleration or negative

A graph that shows speed versus time is not an acceleration graph.The slope of the graph at any point is the acceleration at that time.A straight line shows that the acceleration is constant.
