With this velocity-time graph, sketch over the position-time graph for it. Please help?

Given the velocity-time graph, let's sketch a position-time graph on the same grid.
We have the following:
From t = 0 to t = 2, there was constant acceleration.
From t = 2 to t = 5, there was constant velocity.
From t = 5 to t = 10, there was constant acceleration
From t = 10 to t = 19, the object was deccelerating.
Now, to sketch the position-time graph, we have:
Therefore, the position-time graph and the velocity-time graph are sketched on the same grid above.
