Answer:
B
Step-by-step explanation:
When you simplify the second equation
-2y = 6x + 6
you divide both sides by -2
y = -3x - 3
notice equation 1's slope is 1/3 and equation 2's slope is -3, for the second, it is negative and a reciprocal of the first, that suggests they are perpendicular to one another.
