finding term independent of variable

Express the equation 4x-5y+20=0 in the form so that: (i) x is dependent variable and y is the independent variable. (ii) y is dependent variable and x is independent variable.

The changes in a function y and the independent variable x are related as dy/dx=x^2 . Find y as a function of x.

The changes in a function y and the independent variable x are related as dy/dx=x^2 . Find y as a function of x.

The changes ina function y and the independent variable x are related as dy/dx=x^2 . Find y as a function of x.

The variable used for predicting the response is called the independent variable.
