Answer:
The variables x and y represents the input variable and y represents the output variable.

Consider the provided information.
When the bivariate data are the result of two quantitative variables, it is customary to express the data mathematically as ordered pairs ( x, y),
In mathematics or algebra x is the input variable or we can say that the independent variable.
y is the output variable or we can say that the dependent variable.
Therefore, the variables x and y represents the input variable and y represents the output variable.
