A vertical line is a line on the coordinate plane where all the points on the line have the same x-coordinate. The equation of a vertical line is given by x = a, or x = -a, where x is the x coordinate of any point on the line and a is where the line cros
Horizontal lines and vertical lines both adhere to linear equations. The typical equation of a straight line is {eq}y=mx+b {/eq}. Here, m is the slope and b is the y-intercept. The slope is given by the slope formula from above: {eq}m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}...
To write the equation of a horizontal line, we only need to specify where it intersects with they-axis.This will look likey=k,wherekis where the line crosses they-axis. y=k Made usingDesmos Can we reach this conclusion from thestandard formof linear equations? The answer is yes. A line...

The slope of a vertical line is undefined because the denominator of the slope (the change in X) is zero. Vertical lines help determine if a relation is a function in math. The equation of a vertical line always takes the form x = k, where k is any number and k is also the x...
Example 1: Identifying if a Given Equation Is a Function Graph the line with an equation y2 = -5x and show it is a function. Solution By observing the equation itself, we can infer that the graph of the function is a parabola opening to the left. Now, to make sure of it, let us...
A heuristic account is given of the author''s personal investigation of some aspects of the vertical line and point symmetries of differentiable functions. Starting from examples of third degree polynomials there is first generalized to polynomials in general, and later even more generally to differen...
Because the graph will be nearly equal to this slanted straight-line equivalent, the asymptote for this sort of rational function is called a "slant" (or "oblique") asymptote. The equation for the slant asymptote is the polynomial part of the rational that you get after doing the long ...
What is the vertical line test?The Vertical Line TestIn mathematics, a function describes a relationship between two variables and is often represented using an equation or a graph of an equation. Not all equations or graphs are functions, however, and this is where the vertical line test ...
What are horizontal and vertical asymptotes? They are horizontal and vertical lines that the function approaches forever. The graph of the function will approach such line but without ever touching it.Asymptotes of a Function Graphs of functions are like an art piece. They may be linear, curved...
