Answer:
Neither
Explanation:
Rearrange 8x+2y=-6 to y-intercept form
2y = -8x - 6
y = -4x - 3
y=4x-1 has a slope of 4.
A line perpendicular to this would have the slope -1/4.
A line parallel to this woud have the same slope, 4.
8x+2y=-6 has a slope of -4.
Therefore, 8x+2y=-6 is neither perpendicular nor parallel to y=4x-1.
