Question

True or false. A position-time graph can tell in which direction the displacement of an object is.

Answer 1

If i get it right, the values in graph are either + or -. So bassically you can tell wether the object is increasing the gap from it's starting position or decreasing it, but wich direction he is moving (left, right, up, down, etc.) isn't really clear.
So therefore I would say no, it can't.

Answer 2

false

Answer 3

What do you think? Can you calculate the direction of the displacement from this graph?
