How is the velocity of an object calculated using a displacement vs. time graph? a. By finding the x and y values for any point on the graph. b. By calculating the slope between two points on the graph. c. By finding the x and y points for any two poin

The correct answer is: **b. By calculating the slope between two points on the graph.** In a displacement vs. time graph, the velocity of an object is represented by the slope of the line. The slope is calculated by taking the change in displacement (y-axis) divided by the change in time (x-axis) between two points on the graph.
