Final answer:
The equations y = -3/7x + 4/7 and y = -3/7x - 5 are neither parallel nor perpendicular to each other.
Step-by-step explanation:
The equations y = -3/7x + 4/7 and y = -3/7x - 5 are not parallel, perpendicular, or skew to each other.
To determine if two lines are parallel, we compare their slopes. In this case, both equations have the same slope of -3/7, so they are not parallel. To determine if two lines are perpendicular, we compare the product of their slopes. In this case, the product of -3/7 and -3/7 is not -1, so they are not perpendicular.
Therefore, the correct answer is neither parallel nor perpendicular.
