B.
y = -6
C.
y = 6x
D.
y = x

Answer 1

B

Explanation:

A line perpendicular to the y- axis is a horizontal line parallel to the x- axis, with equation

y = c ( where c is the value of the y- coordinates the line passes through )

y = - 6 → B

Answer 2

B. y = -6

Explanation:

As you can see the graph I done is perpendicular
