A time graph reveals specific information on the velocity (change in position with respect to a change in time).
So, on a position - time graph, the feature representing motion in the negative direction over time is a downward sloping line segment.
A slope in a position time graph depicts the velocity also called the slope in this type of graph as it the change in position over time.
So, a downward sloping line segment feature in a time graph indicates that the motion of the object is in the negative direction. While a positive sloping line segment indicates otherwise.
