Having a real hard time figuring out the position-time graph and the acceleration-time graph from the given velocity-time graph. Any hints,or suggestions, would be greatly appreciated.

What is the acceleration when v=o m/s? Explain.

Do you know how to do integrals and derivatives? The position/time graph is simply the integral of the velocity/time graph, and the acceleration/time graph is the derivative of the velocity/time graph.
Edit: You can't find the acceleration from just the velocity alone. If you can see where on your graph you have a velocity of 0 m/s, the acceleration is the slope of the line at that point. But note that this slope could be anything - the mere fact that the velocity is 0 m/s has no bearing on the acceleration.

There is a very easy way. remember the units for all the quantities like acceleration is m/s2, velocity & speed is m/s, thus for a graph the slope is diff in yaxis by diff in x axis. So for a Displacement(m)-Time(s) graph slope is m by s= m/s(velocity) & for a velocity(m/s) time (s) graph slope is acceleration(m/s*1/s)(m/s2).
Hope that clarifies your doubt

if a vel-time graph is a straight line parallel to x axis (horizontal)
then it doesn't change accelerate with time , so, acc=0
If it is diagonal, straight i.e. increases with time, there is an acc and it is the slope of the graph. i.e. change in vel divided by the respective change in time.
