The first graph represents the length of a necklace being made without any breaks at a constant rate of 10cm/hour.
The second graph represents the height of a balloon that is rising but gets caught in a tree for a few minutes, causing the height to stop increasing. Once the balloon is freed, it continues to rise at a steady rate.
