Answer:
Here: Note *I can't see the graph*
Explanation:
Since the line is irregular, it is not linear, meaning that it is not a straight line. However, in general, it means that the amount the function increases in a certain period is smaller than how much it decreases later on.
You can just write the graph decreases more than it increases or that, in general, when the x value increases, the y value decreases. This should be what defines a negative trend even if the graph isn't fully linear.
