Answer
Parallel
Work Step by Step
We are given the lines
$y=12x+6$
$y=12x-2$
These line is 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 have a slope of 12 and a different y-intercept, so they must be parallel.
