Answer:
The useful information that the configuration of the y-axis provides the reader:
The y-axis or the vertical line shows the dependent relationship that exists between its variables and the variables of the x-axis (the horizontal line). It shows the reader how much the values on the y-axis depend on the variables of the x-axis.
Explanation:
On a graph, the y-axis shows the dependent variables or values which depend on the variables of the x-axis. At the starting point or the zero coordinate, the y-axis and the x-axis are equal to zero. However, as the x-axis increases in value, the values of the y-axis are then defined on the increasing values of the variables in the x-axis. This implies that an experimenter chooses the values on the x-axis but does not determine the values that are on the y-axis. Instead, she uses the values or variables lying on the x-axis to calculate the values on the y-axis.
