Answer:

$x=(-12,0)$

$y=(0,3)$

Step-by-step explanation:

x-intercept

$-2(x-4y)=24$

$x-4y=-\frac{24}{2}$

$x-4y=-12$

$x=4y-12$

$x=4(0)-12$

$x=-12$

y-intercept

$-2(x-4y)=24$

$x-4y=-\frac{24}{2}$

$x-4y=-12$

$-4y=-12-x$

$y=-\frac{-12-x}{4}$

$y=-\frac{-12-(0)}{4}$

$y=\frac{12}{4}$

$y=3$
