What does the slope of a velocity-time graph indicate?

The slope of a velocity-time graph indicates the acceleration of the object. Acceleration is defined as the rate of change of velocity with respect to time. On a velocity-time graph, the slope of the line represents this rate of change. A steeper slope indicates a greater acceleration, while a shallower slope indicates a smaller acceleration. If the slope is positive, the object is accelerating in the positive direction. If the slope is negative, the object is accelerating in the negative direction.
