A vertical line is a line that is placed perpendicular to the surface or on another line that has been considered as the base. In a graph paper, and in coordinate geometry, the vertical lines are placed parallelly to the Y-axis on the graph.
So, a vertical line will always be a straight line that is drawn from top to bottom and not sideways. In a square or a rectangle, vertical lines are those lines that make the formation with the base. Now, let us know about the definition of Vertical line and its example.
Definition of a Vertical Line
A vertical line is a definite line that lies on the coordinate plane where all the points on the line will be on the same coordinate axis that is on X-axis. Thus, when you plot the vertical line, we will find that a vertical line is obtained by joining all the coordinate points on the same axis. Suppose p1 and p2 are the vertical lines then the point will be on the X-axis, for the value of y while all the other points of L2 will be on the coordinate lines.
Vertical Lines Structuring on a Coordinate Plane
The quadrants which are passing through the vertical lines are identified as the same quadrants which are lying on the same points. Suppose, the coordinates are being denoted by p and q then the value of y and x will be constant throughout.
What Will be an Example of a Vertical Line?
In the graph which is shown, the values of y and the x will be supposed 8, Then the vertical line is 8 units which are aways from the origin point which is placed towards the right, and then the parallel to the y-axis they the coordinates will be (8,0), (8, -1), etc, these all points lie on the vertical line.
What is a Straight line?
The best description of a straight line is that it is a one-dimensional figure where the width of the structure does not exist at all. This straight line will never have a curve. This straight line has endless points joined on both sides of this point. So, a straight line can be a vertical line, a horizontal line, a vertical, or a slanted line. Suppose, there are two points, any line which will be passing through these points will form a 180 degree.
So, to define more precisely we can say that a straight line is an infinite length of line that does not have any curves. This straight can be a meeting source of two points or it can also be extended to an infinite region.
The coordinates of a straight line can be the points that are being placed in a graph. Suppose points a and b in a straight line on a coordinate graphic form will represent a straight line.
What are the Types of Straight Lines?
Straight lines can be of many types. The types of straight line can be classified based on the alignment. An alignment refers to the point of angle which is formed of the X-axis and the y-axis. Thus, according to the angle or alignment of a straight line, the following are the types of a straight line:
- Horizontal Lines
- Vertical Lines
- Slanted or the Obliqued lines
What Will be the Equation of the Straight Line?
The equation of the straight line is very simple if we study the relation of x and y on the curve point. Thus, the general equation of a straight line will be –
ax + by + c = 0, where x and y are the variables while a, b and c are the consonants. Further to know more about the amazing concepts and equations, visit Cuemath for a great exploration of your favorite subject mathematics.
