Based on your description of the graph, it sounds like the motion of the object is represented by a small "L" shape with a diagonal line going upwards from the crease.
The vertical axis is labeled "Speed" while the horizontal axis is labeled "Time." The shape suggests that the object starts from rest (0 speed at time 0), represented by the bottom of the "L." The diagonal line indicates that the object's speed is increasing with time as it moves.
Given these observations, the correct statement would be:
The object starts at rest and then accelerates at a constant rate.
This is because the diagonal line implies a constant increase in speed over time, indicating consistent acceleration.
