Vertical Line
A line that runs straight up and down,
A vertical line is a straight line that extends infinitely in both directions. It is perpendicular to the horizontal line and has an undefined slope. The equation of a vertical line is written as x=a, where ‘a’ is the x-coordinate of any point on the line. This means that all points on this line have the same x-coordinate.
Graphically, a vertical line can be represented as a line that goes straight up and down. It can be used in various mathematical applications, such as linear equations, coordinate geometry, and graphing functions.
One interesting fact about a vertical line is that it has no y-intercept, which means that it does not intersect the y-axis at any point. Hence, its equation cannot be written in the form of y=mx+b.
In real-life scenarios, vertical lines may represent structures such as trees, lampposts, buildings, or other objects that stand upright and extend from the ground up into the sky.
