Question

For equation given below, name the dependent and independent variables.

$y=\frac{4}{3}x-7$

• A. $x$ independent, $y$ independent.
• B. $x$ independent, $y$ dependent.
• C. $x$ dependent, $y$ dependent.
• D. $x$ dependent, $y$ independent.

Answer 1

Answer: (B)

$x$ independent, $y$ dependent.

In the equation, $y=\frac{4}{3}x-7$; the variable $x$ can take any value. With the different values of $x$, we get different values of $y$.
Hence, $x$ is the independent variable and $y$ is the dependent variable.
