Answer
The statements that can be supported by using a position time graph are;
• A negative slope results when an individual is moving towards the origin.
• A positive slope results when an individual is moving away from the origin.
• The slope of the line gives the velocity of the individual.
Explanation
The vertical axis of the position time graph represent the position of the object. The slope of a position graph represent the velocity of the object. When the line representing the gradient is horizontal, the velocity is zero and the object is momentarily at rest. A curvature in a position time graph represents an accelerating object.
