Question

analyze the graph and complete the statements that follow.
average monthly rainfall
graph: x - axis (month: jan, feb, mar, apr, may, jun, jul, aug, sep, oct, nov, dec); y - axis (rainfall (inches): 0, 10, 20, 30, 40); line graph showing rainfall trends
the greatest amount of rainfall was recorded in the month of ▼.
the least amount of rainfall was recorded in the month of ▼.
the relationship between time of year and amount of rainfall is ▼.

Explanation:

Step1: Identify the peak for greatest rainfall

Looking at the graph, the highest point (peak) of the rainfall curve is in May. So the greatest amount of rainfall was recorded in May.

Step2: Identify the trough for least rainfall

The lowest point (trough) of the rainfall curve is in January and April (both at 0 or near 0). But typically, January is the first month with 0, so the least amount of rainfall was recorded in January (or April, but January is a common pick here).

Step3: Analyze the relationship

The graph shows that rainfall varies (increases, decreases, then fluctuates) with the time of year, so the relationship is that rainfall varies (or is non - linear, or has fluctuations) with the time of year (it's not a simple linear relationship, it has peaks and troughs).

Answer:

The greatest amount of rainfall was recorded in the month of $\boldsymbol{May}$.
The least amount of rainfall was recorded in the month of $\boldsymbol{January}$ (or $\boldsymbol{April}$).
The relationship between time of year and amount of rainfall is $\boldsymbol{that\ rainfall\ varies\ (fluctuates)\ with\ the\ time\ of\ year}$ (or a description like "non - linear" or "has peaks and troughs" depending on the expected answer format).
