Answer
$y=\frac{1}{2}x-6$
Work Step by Step
The given line has a slope of $\frac{1}{2}$ and a y-intercept of (0,-6). We can write this line in the slope-intercept form $y=mx+b$ (where m is the slope of the line, and the point $(0,b)$ is the y-intercept).
In this case, $m=\frac{1}{2}$ and $b=-6$.
Therefore, $y=\frac{1}{2}x-6$.
