Answer:
the right answer is y= -2
Step-by-step explanation:
y = -2 because, x = -6 where it should be noted that it is a vertical line since in all its points within the plane -6 it will always be constant, to be able to find a line perpendicular to this we must find one that is horizontal, with points (-1,-2). we notice that its constant point on the Y axis will always be -2, which will always be made by a horizontal line and therefore perpendicular to the other.
