Which equation represents a vertical line ?
y = -x
y = 12
x = y
x = 12

Answers

Answer 1
Answer: y is a vertical axis
x is a horizontal axis
when drawing a line, the line drawn to them is perpendicular so lines only touching the x axis are vertical and lines touching only the y axis are horizontal

the
a vertical line is x=value

the only thing that works is x=12
Answer 2
Answer: A vertical line is any line in which x is constant.  The line x=12 is vertical, because x is ALWAYS equal to one number - it doesn't change, ever.
