If the axes are time/distance then, and only then, it means a constant velocity
If not, then this Q doesn't have enough data to A
It means that the object in question is moving at a constant speed.If the graph is a straight horizontal line, then the speed is zero.
A straight line graph (on the cartesian or coordinate plane).
Constant speed. Zero acceleration.
BecAuse that would mean it is going an infinite speed. The slope of a distance time graph is the objects velocity or speed. If there is a line parallel to the distance axis, there is a vertical line. The slope of a vertical line is infinite. It is not possible to go an infinite speed.
This means your velocity is decreasing with time, or in other words, the object is slowing down.
Time is plotted on the X-axis. Speed or velocity is plotted on the Y-axis. A straight horizontal line on a speed-time graph means that speed is constant. It is not changing over time. A straight line does not mean that the object is not moving!
Look for the key to the symbols on your graph, which will explain the straight line.
It means that the object in question is moving at a constant speed.If the graph is a straight horizontal line, then the speed is zero.
Many sets of data do not form into straight lines. If by "What if" you mean how to plot a line onto this graph. Then simply draw a curved line of best fit.
horizontal
It means acceleration.
y axis
A straight line graph (on the cartesian or coordinate plane).
If acceleration is negative the graph looks like a upside U and decreases in value as time continues If acceleration is constant the graph is a straight line (linear) at 0 or whatever the velocity is

That an object is losing speed. It is experiencing negative acceleration.
