Answer: The correct answer is the dependent variable
Step-by-step explanation:
A dependent variable is defined a the variable whose value changes with respect to the change in the independent variable. In a graph, it is always written on the y-axis.
An independent variable is defined as the variable which does not changed with respect to any variable. In the graphical representation, it is always written on the x-axis.
A direct relationship is defined as the relationship in which if one variable changes, the other variable also changes. If one increase, the other variable also increases and vice-versa.
In the graph, position 'm' is written on the y-axis and hence, is considered as a dependent variable.
