straight line
The graph is a straight line. Its slope is the speed.
A horizontal line on a speed vs time graph indicates constant speed.
That kind of depends on what is being graphed. -- On a graph of acceleration vs time, the graph is a straight line that lays right on top of the x-axis, because the acceleration is a constant zero. -- On a graph of speed vs time, constant speed is a horizontal line, parallel to the x-axis. -- On a graph of distance vs time, constant speed is a straight line with a positive slope; that is, it rises as it progresses toward the right.
yes
By using the distance, speed, and acceleration, to show on the graph the constant speed of each car
Constant speed is shown on a graph using straight lines. The straight line indicates that there are no fluctuations with the speed.
On a graph of velocity and time, a constant speed would appear as a straight horizontal line.
On a V-t graph, constant speed is shown as a horizontal line.
The graph is a straight line. Its slope is the speed.
I would like to state first that you misspelled horizontal. The answer to your question is Constant speed.
At constant speed, the distance/time graph is a straight line, whose slope is equal to the speed.
A horizontal line on a speed vs time graph indicates constant speed.
If the line formed by the graph is straight, the speed is constant. A horizontal line would show the object as stationary.

Constant speed..
yes
it means the object is moving at a constant speed
