Which statements can be supported by using a position-time graph? Select three options.
A negative slope results when an individual is moving toward the origin.
A horizontal line on the graph means the individual is moving at the same velocity.
A positive slope results when an individual is moving away from the origin.
The slope of the line gives the velocity of the individual.
The speed of an individual cannot be determined from this type of graph.
