# what is the slope of the line 12x+4y=24?

$12x+4y=24\ \ \ \ /-12x\\\\4y=-12x+24\ \ \ \ /:4\\\\y=\frac{-12}{4}x+\frac{24}{4}\\\\y=-3x+6\\\\Answer:the\ slope\ is\ m=-3$
$12x+4y=24 \\ \\ the \ slope \ intercept \ form \ is : \\ \\ y= mx +b \\ \\ 4y =-12x+24 \ \ / :4 \\ \\y=-\frac{12}{4}x+\frac{24}{6}\\ \\y=-3x+ 4 \\ \\Answer : \ the \ slope \ m =-3$
