On a distance-versus-time graph, _____.
A.) the steeper the slope of the line, the faster the speed of the object

B.) if the line has a constant slope, the speed may be changing

C.) slope is calculated by dividing the run by the rise

D.)if the slope is zero, the object is moving slowly

Respuesta :

Answer:

A

Explanation:

The slope of the graph has the units of vertical axis divided by horizontal axis. This means that the slope of a distance vs time graph is distance/time, or velocity.

Slope is calculated by "rise over run" so C is incorrect.

Since the slope represents velocity, a constant slope equates to a constant velocity, hence B is incorrect. Same reasoning for D being incorrect: if the slope is zero, the object is not moving.
