Write story or description about what the graph shows . my brain cells are dying

I would say something along these lines: You are walking along a path, and then someone follows you. You then jog a little faster, but the stalker is coming. You then start to run away from the stalker. You realize that you are taking too long, so you jump on a bicycle. The stalker goes in a bicycle, so you jump onto a moving train to get away from him without stopping.

I would probably wrote something of this sort >  Matt Skateboarded from his home, Gradually Building Up speed.  Matt Slowed down to avoid, some rough ground, but then Matt Speeded up again.

The slope gets Steeper with Time.  This means the objects  velocity is Increasing. (The Increasing Displacement means it's going away from you).

Hope that helps!!!                             : )

b. b < 1 might be the correct answer
