Which of the equations below represents a line perpendicular to the y-axis?

O A.

y = 6x

B. y = - 6

C.

x = 6

D.

y=x

B. y = - 6

Step-by-step explanation:

You can graph each line to see which one is horizontal since the y-axis is vertical. This would make the lines perpendicular since when a vertical and horizontal line meet, they form a 90-degree angle, which is by definition what perpendicular means.
