How do you show a car constant speed
Horizontal line or vertical
To represent a car moving at a constant speed on a graph, you would use a horizontal line.
Explanation:
A horizontal line on a graph represents a constant value or a change that does not vary with respect to time. In the case of a car traveling at a constant speed, its position does not change over time. Thus, the graph of its position vs. time would be a straight, horizontal line. This is because the position of the car remains the same as time progresses, indicating a constant speed.
On the other hand, a vertical line on a graph represents a variable that changes instantaneously. For example, if you were graphing the speed vs. time of a car, a vertical line would indicate an instantaneous change in speed, rather than a constant speed.
