$x$	$y$
$-9$	$0$
$0$	$-144$
$\frac{8}{3}$	$0$

The table shows three values of $x$ and their corresponding values of $y$. There is a quadratic relationship between $x$ and $y$. An equation that represents this relationship can be written as $y=6x^2-bx-144$, where $b$ is a constant. What is the value of $b$?
