Answer with Explanation:
The <em>peak, trough, recession and recovery</em> are stages of the "Business Cycle." They can be represented in a line graph as points that represent individual stages. Each can tell what a country's economy is experiencing in terms of fluctuations happening in economic activities.
The peak is that highest point in the graph. It means that the economy is producing the maximum output that it is allowed to do so.
The trough is the lowest point in the graph. This marks the<em> end of depression.</em> This means that soon, the<em> economy will try to recover.</em>
The recession is that point on the graph that goes down following the peak. This is a period of economic decline or contraction. Here, the production decreases.
The recovery is that point on the graph that goes up following the trough. This stage is marked by increase in demand and production. It is considered to be the end of the business cycle.
