What is a Vertical Line

What is a Vertical Line In a coordinate X-Y plane, there are two main axes which are always fixed. They are the X-axis and the Y-axis. The X-axis is the horizontal line and the Y-axis is the vertical line. In the coordinate plane, any axis parallel to the Y-axis is also known as the vertical line. Given any point on the plane, a vertical line can be drawn passing through the given point. Based on the point, the equation of the vertical line can be calculated. Example 1: On which line are the points (0, 3) and (0, 5) located? Given two points: (0, 3) and (0, 5) Hence for the point (0, 3), the x-coordinate = 0 and y-coordinate = 3. Similarly, for the point (0, 5), the x-coordinate = 0 and the y-coordinate = 5. We can see that both the points have the x coordinate as 0 which means that the points are on the Y-axis as only on Y-axis, all the x-coordinates of the points are 0. Example 2: On which line are the points (0, -1) and (0, -6) located? Given two points: (0, -1) and (0, -6) Hence for the point (0, -1), the x-coordinate = 0 and y-coordinate = -1 Similarly, for the point (0, -6), the x-coordinate = 0 and the y-coordinate = -6. We can see that both the points have the x coordinate as 0 and hence the points are located on the Y-axis. This Y-axis is the vertical line continuing up and down until positive infinity and negative infinity.
