Answer :
The given question is incomplete as the graph is missing.
But, considering a line graph, the following parameters can be represented on the x-axis and y-axis:
X-Axis Y-Axis
Year Population
Time Number of employees hired
Identical items purchased Total cost in dollars
What does the blank observed line represent in each graph?
The blank observed line represents the time. A line graph is basically used to connect the quantitative values over the different time intervals. The change in values over time is easier to estimate, by the help of the line graph. For example: in a graph showing the year on the x-axis and the population on the y-axis, the blank line represents the change in population over the years, the increase or decrease or the rate of change.
