Let’s check out your problem:

The function $g$ is defined by $g(x)=\frac{1}{m} x+21$, where $m$ is an integer constant and $14 \leq m \leq 17$. For the graph of $y=g(x)-9$ in the $x y$-plane, what is the $x$-coordinate of a possible $x$-intercept?$\newline$A) $-168$$\newline$B) $-192$$\newline$C) $-204$$\newline$D) $-216$
