How is the velocity of an object calculated using a displacement vs. time graph? A. calculating the area under a line segment on the graph. B. By finding the x and y points for any two points on the graph. C. By finding the x and y values for any poin

The correct answer is: **D. By calculating the slope between two points on the graph.** In a displacement vs. time graph, the slope of the line represents the velocity of the object. The slope is determined by the change in displacement (vertical axis) divided by the change in time (horizontal axis) between two points on the graph.
