For each equation given below; name the dependent and independent variables.

(i) $y = \dfrac{4}{3}x - 7$

(ii) x = 9y + 4

(iii) $x = \dfrac{5y + 3}{2}$

(iv) $y = \dfrac{1}{7}(6x + 5)$

(i) $y = \dfrac{4}{3}x - 7$

In the above equation, the value of y depends on the value of x, so y is said to be dependent variable and x is said to be independent variable.

Hence, x = independent variable and y = dependent variable.

(ii) x = 9y + 4

In the above equation, the value of x depends on the value of y, so x is said to be dependent variable and y is said to be independent variable.

Hence, x = dependent and y = independent.

(iii) $x = \dfrac{5y + 3}{2}$

In the above equation, the value of x depends on the value of y, so x is said to be dependent variable and y is said to be independent variable.

Hence, x = dependent and y = independent.

(iv) $y = \dfrac{1}{7}(6x + 5)$

In the above equation, the value of y depends on the value of x, so y is said to be dependent variable and x is said to be independent variable.

Hence, x = independent and y = dependent.
