The equation of a line parallel to y axis is of the form x = a and it cuts the x-axis at the point (a, 0). This line is parallel to y axis and is at a perpendicular distance of ‘a’ units from the y-axis. The slope of the equation of line parallel to y axis is undefined, since it is inclined at 90º with the x axis.
Let us learn more about how to find the equation of line parallel to y axis, the properties of this line, and check a few examples.

The equation of line parallel to y axis is of the form x = a, and it cuts the x-axis at the point (a, 0). Here all the points on this line parallel to the y-axis will have the same x coordinate of a. Further the equation of line parallel to y-axis and cutting the x-axis at point (a, 0) is at a perpendicular distance of ‘a’ units from the y-axis. The distance between two lines which is a line parallel to y-axis and the y-axis is a units. This equation of line parallel to y axis makes an angle of 90º with the x-axis, and hence its slope is equal to the value of Tan90º, which is undefined.
The equation of line parallel to the y axis and cutting the positive x-axis passes through the first and the fourth quadrant. And the equation of line parallel to the y axis and cutting the negative x-axis passes through the second and the third quadrant of the coordinate axes.

As an example, let us consider the equation of line parallel to y-axis, which is x = 3. This equation x = 3 cuts the x-axis on the positive side at the point (3, 0), and it passes through the first and the fourth quadrant. Further, the points (3, 1), (3, 2), (3, 5), (3, -2), (3, -3), (3, -5), all of these points falling on this line x = 3.
The following are the properties of the equation of line parallel to the y-axis
- The line parallel to y-axis cuts the x-axis at one distinct point.
- The line parallel to the y-axis cuts the x-axis at only one point (a, 0) and has the equation x = a.
- The equation of line parallel to y-axis and cutting the x-axis at the point (a, 0) is at a perpendicular distance of ‘a’ units from the y-axis.
