-- 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.

A constant speed has a slope of zero on a graph because no acceleration is taking place?
That would be true, in the case of a graph of speed vs time.
How is speed and acceleration represented on a graph?
On a speed versus time graph, acceleration is represented by the line on the graph. If acceleration is constant, the line cuts through equally between the axis and starts from the zero point.
How does average speed relate to the shape of the graph?
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.
Can you tell from a velocity-time graph whether an object is stationary?
If the curve is horizontal, then the speed is constant. If that horizontal graph lies on the x-axis, then the constant speed is zero, and the object is stationary.
How would a graph look if the speed is constant?
That would depend on the type of axes. If it is an acceleration vs. time graph, then there would be a continual reading of 0m/s/s acceleration, and the graph would be a straight line indicating 0m/s/s at all times. If it is a velocity vs time graph, then there would be a constant value of velocity at all times. If it is a displacement vs time graph, there would be a straight, continuously increasing line.
A constant speed has a slope of zero on a graph because no acceleration is taking place?
That would be true, in the case of a graph of speed vs time.
If a graph shows time on the horizontal axis and speed on a vertical axis a straight horizontal line across the graph would indicate?
Constant speed ... zero acceleration.
For motion along a straight line a horizontal line on a speed over time graph indicates graph indicates that what is zero?
For motion at constant speed along a straight line, the acceleration is zero.
If a graph shows time on the horizontal axis and speed on the vertical axis a straight horizontal line across the graph would indicate what?
The graph you described is a speed-time plot. If the line is horizontal, that indicates no change in speed over time. In other words, there is no acceleration (acceleration is zero), since there is no change in speed.
How is speed and acceleration represented on a graph?
On a speed versus time graph, acceleration is represented by the line on the graph. If acceleration is constant, the line cuts through equally between the axis and starts from the zero point.
What does a straight line mean in a distance time graph?
Constant speed. Zero acceleration.
How does average speed relate to the shape of the graph?
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.
How would you graph -3 on the numberline?
To graph a negitive . You would go three spaces back from zero.
Can you tell from a velocity-time graph whether an object is stationary?
If the curve is horizontal, then the speed is constant. If that horizontal graph lies on the x-axis, then the constant speed is zero, and the object is stationary.
Why does a constant speed have a slope of 0 on a graph of speed v time?
Because a slope of zero indicates that the y-value (speed) isn't changing.
On a speed-graph a horizontal line shows the change in speed is what?
Constant speedThe graph you described is a speed-time plot. If the line is horizontal, that indicates no change in speed over time. In other words, there is no acceleration (acceleration is zero), since there is no change in speed.
