$y = - 8$ $y=-8$

Explanation:

$the initial statement is y \propto x$ $"the initial statement is "ypropx$

$to convert to an equation multiply by k the constant$ $"to convert to an equation multiply by k the constant"$
$of variation$ $"of variation"$

$\Rightarrow y = k x$ $rArry=kx$

$to find k use the given condition$ $"to find k use the given condition"$

$y = 4 when x = 12$ $y=4" when "x=12$

$y = k x \Rightarrow k = \frac{y}{x} = \frac{4}{12} = \frac{1}{3}$ $y=kxrArrk=y/x=4/12=1/3$

$"equation is " color(red)(bar(ul(|color(white)(2/2)color(black)(y=1/3x)color(white)(2/2)|)))$

$"when "x=-24$

$y=1/3xx-24=-8$
