Final answer:
Zach could plot data in Quadrant IV if he records temperatures that drop below zero after noon, which might occur in a desert region during winter evenings.
Step-by-step explanation:
Zach could collect data in Quadrant IV of the coordinate plane where the x-values, representing the number of hours since noon, are positive and the y-values, representing temperature, are negative. This scenario is typical in regions experiencing cold weather patterns during the evening hours. For instance, Zach might be in a desert region where the temperature can drop significantly after sunset. The time of year would likely be winter when temperature drops are more pronounced post-sunset.
To graph such data, Zach would begin by plotting the x-axis with time increments since noon and the y-axis with temperature readings. All plotted points would fall into Quadrant IV if the times recorded are after noon (positive x-values) and the temperatures are below zero (negative y-values), indicating the decrease in temperature as the day progresses into the evening and nighttime.
A real-world example might involve Zach observing the temperature from noon to midnight during a winter month in a desert region. As the hours pass (x-value increases), the temperature could fall below the freezing point (y-values become negative), thereby placing the plotted points in Quadrant IV, where both axes meet with positive x and negative y values.
