The word linear is used for a straight line. A linear function is a function of a straight line, which means that the degree of a linear function must be $0$ or $1$ . In this case, The degree of $f (x) = \frac{x^{3} - 7 x + 1}{8 x - 9}$ is $- 1$ , which makes the function a nonlinear function.

$f (x) = \frac{x^{3} - 7 x + 1}{8 x - 9}$ is not a linear function
