Question

in a distance - time graph, the ______ axis shows time.
vector
vertical
horizontal

Explanation:

In a distance - time graph, the independent variable (time) is typically plotted on the horizontal axis (x - axis), while the dependent variable (distance) is plotted on the vertical axis (y - axis). A vector is a quantity with magnitude and direction and not an axis. "Track" is not a standard term for an axis in a graph.

Answer:
