On a position-time graph, why does the x-axis only show positive values?(1 point)

The x-axis shows the motion of an object, and motion cannot be assigned a negative value on a position-time graph.

The correct response is:

The x-axis shows time, and time cannot be assigned a negative value on a position-time graph.

In a position-time graph, the x-axis typically represents time, which is inherently non-negative in physical scenarios because time progresses forward and does not go into negative values.
