The slope intercept form of a line is:
y = mx + b
Where
m is slope
b is y intercept
Let's rearrange this equation into slope-intercept form:
[tex]\begin{gathered} 2y+x=-12 \\ 2y=-x-12 \\ y=-\frac{x}{2}-\frac{12}{2} \\ y=-\frac{1}{2}x-6 \end{gathered}[/tex]
From this form, we can say:
Slope is -1/2
Y-intercept is -6
The graph is shown below:
