Question

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

Answer 1

Answer:

Option B

Step-by-step explanation:

we know that

A line perpendicular to the x-axis is a line parallel to the y-axis

so

the equation of the line is of the form x=(+/-)a

The slope of the line is undefined

where

a is a real number

therefore

x=6 is a line perpendicular to the x-axis

Answer 2

Answer:

B. $x = 6$

Step-by-step explanation:

The x-axis is the line of $0 = y$ [horizontal line], therefore the ONLY live perpendicular to that would be $x = 6$, which is a vertical line, giving you a right angle in the centre.
