-- 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.
If an object is not moving, its speed-time graph would be a horizontal line at the zero speed level. This is because the speed of the object is constant at zero, indicating that it is not experiencing any motion or changes in speed over time.
That would be true, in the case of a graph of speed vs time.
A horizontal line on a velocity-time (V-T) graph would show constant speed. This is because the slope of a V-T graph represents acceleration, and a horizontal line means zero acceleration, indicating constant speed.
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.
Yes, you can have a situation where an object has a non-zero velocity but zero acceleration. This occurs when the object is moving at a constant speed in a straight line. On a velocity-time graph, this would be represented by a horizontal line at a non-zero velocity value and a flat line at zero acceleration.

Constant speed ... zero acceleration.
That would be true, in the case of a graph of speed vs time.
A horizontal line on a velocity-time (V-T) graph would show constant speed. This is because the slope of a V-T graph represents acceleration, and a horizontal line means zero acceleration, indicating constant speed.
For motion at constant speed along a straight line, the acceleration is zero.
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.

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.
To graph a negitive . You would go three spaces back from zero.
Constant speed. Zero acceleration.
Speed is represented by the slope of a distance-time graph, where steeper slopes indicate faster speed. Acceleration is represented by the slope of a speed-time graph, where a steeper slope indicates a greater acceleration.
Because a slope of zero indicates that the y-value (speed) isn't changing.
