Vertical lines cannot be written in standard form because the slope is undefined. The equation of the line is given by the x-intercept of the line. In this case x=0 goes though the origin (x=0), which means this is the equation of the y-axis.

Explanation:
1. x = 0 is an equation of a vertical line passing through the point where x = 0.
2. This vertical line is called the y-axis.
3. The equation x = 0 means that the value of x is always 0, regardless of the value of y.
4. Therefore, all points on this line have an x-coordinate of 0 and vary in their y-coordinates.
5. In a Cartesian coordinate system, the y-axis is perpendicular to the x-axis and is used to represent the values of y in a coordinate pair.
6. Thus, the equation x = 0 represents the y-axis in the coordinate plane.
7. The correct answer is option 'D' - y-axis.
