Answer:
perpendicular
Step-by-step explanation:
The slope of y = 3x - 7 is 3.
3x + 9y = 9 → 9y = -3x + 9 → y = -1/3 x + 1 so its slope is -1/3.
This means that they are perpendicular because the product of their slopes is -1.
The answer is 12 because the lines of the parrellel shape he’ll come across each other
I believe the answer is # 4
