A speed graph has a slope that is greater than zero that is shown on an object accelerating. Graphs that show straight means constant speed and is kept at a negative slope.
-- If the position/time graph is a straight line, then the speed is constant, and the slope of the line is the average speed, as well as the instantaneous speed at any moment. -- If the position/time graph is not a straight line, then the average speed between two moments in time is the slope of a straight line drawn between those two points on the graph.
The slope of the line between two points on the distance/time graph is the same as the average speed during the time interval between those points.
-- If the graph displays speed against time, then speed of zero is indicated wherever the graph-line touches the x-axis. -- If the graph displays distance against time, then speed of zero is indicated wherever the graph-line is horizontal. -- If the graph displays acceleration (magnitude) against time, then the graph can tell you when speed is increasing or decreasing, but it doesn't show what the actual speed is.
deceleration or negative
The slope of the ant's displacement vs. time graph The total displacement divided by the time.
If speed changes, then the speed/time graph has up/down curves in it.
If you graph distance vs. time, the slope of the line will be the average speed.
If a body is moving with variable speed, then the only thing you can say aboutits speed/time graph is that the graph is not a straight, horizontal line.
The shape and slope of the line on a graph illustrates the qualitative and quantitative relationship between the variables plotted on the axes of the graph. Sadly, there is no such graph as a "speed or time" one.
Assuming it's a graph of speed vs time, then between 2 times, the average is the distance (= area under the graph between those times) divided by the time difference.

Average speed = Distance covered/Time taken
The graph is a straight line whose slope is the acceleration of gravity.

To find the average speed or rate of something.(:
The slope of the line between two points on the distance/time graph is the same as the average speed during the time interval between those points.
