Answer:
The lines are parallel
Explanation:
y = 3x - 12
2y = 6x + 4
Parallel lines have the same slope, perpendicular lines have inverse slopes, and other lines have no correlation in the slopes.
We can simplify the second equation
2y/2=(6x+4)/2
y=3x+2
You can now see that both lines have the same slope, meaning that they are parallel.
y = 3x - 12
y = 3x + 2
