I think the acceleration graph would be constant at -9.8 so it wouldn't be positive. Wouldn't all of them be negative? Because velocity is a vector quantity so it takes into account direction.
I don't know.. I've been thinking about this one for a while and I'm still stuck. Maybe it's just my mind turning to mush
Consider again three graphs for the motion of a skydiver who is affected by acceleration due to gravity and by air resistance:
1. an acceleration versus time graph for the falling skydiver
2. a velocity versus time graph for the falling skydiver
3, a displacement versus time graph for the falling skydiver
Which of the graphs have a positive slope?

well I got it wrong and im sad now
maybe too late but ...
due to air resistance , the diver reaches "terminal velocity"
... the resistive force of the air equals the gravitational force
... acceleration declines to zero , velocity becomes constant
the only thing constantly increasing is the diver's displacement
... displacement (from the jumping point) increases constantly
