Name the INDEPENDENT variable from the table below.

Hint:

In a given equation, the 2 variables viz. x & y can be bifurcated into Independent variable and dependent variable.
The independent variable can be referred to as the cause i.e. Its value is independent (does not change as per the other variables) of other variables. The dependent variable can be referred to as the effect. Its value depends on changes in the independent variable.
Generally, Independent variables are represented on the x-axis i.e. horizontal axis and Dependent variables are represented on the y-axis i.e. vertical axis.
