#### Answer

Neither

#### Work Step by Step

We are given the lines
$y=2x-12$
$y=\frac{1}{2}x-6$
These lines are written 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). These lines both different slopes, so they cannot be parallel. We can check if these lines are perpendicular by seeing if the product of their slopes equals -1.
$2\times\frac{1}{2}=1\ne-1$
Therefore, these lines are neither parallel or perpendicular.
