In geometry a vertical line is one which runs from up and down the page.
Vertical line math.
Is a way to determine if a relation is a function.
Hence any line parallel to the y axis is a vertical line.
In math the y axis is considered vertical.
Its cousin is the horizontal line which runs left to right across the page.
The vertical line test supports the definition of a function.
This has an undefined slope.

Location of the vertical line on the x axis specified as a scalar you can specify xvalue as a numeric categorical datetime or duration value however the type of value you specify must match the data type for the values along the x axis.
Given below are some examples.
No matter what y is x is equal to negative five.
Its equation is x is equal to negative five.
It is a vertical line.
The vertical line test.
If you think about it the vertical line test is simply a restatement of the definition of a function.
Also vertical lines are perpendicular to the x axis.
Xline 12 4 plots the line at x 12 4.
So it s just going to look like this.
The equation of a vertical line always takes the form x k where k is any number and k is also the x intercept.
If we think of a vertical line as an infinite set of x values then intersecting the graph of a relation at exactly one point by a vertical line implies that a single x value is only paired to a unique value of y.
And so notice x never changes.
That is every x value of a function must be paired to a single y value.
For instance in the graph below the vertical line has the equation x 2 as you can see in the picture below the line goes straight up and down at x 2.
Xline d 3 plots the line at the value of the third element in the array.
Vertical lines help determine if a relation is a function in math.
States that if a vertical line intersects the graph of the relation more than once then the relation is a not a function.
A vertical line is perpendicular to a horizontal line.
Sheffer stroke in logic verti bar vbar stick vertical line vertical slash bar pike or pipe and several variants on these names it is occasionally considered an allograph of broken bar see below.
Line l in the given picture is vertical as it is parallel to the y axis.
A vertical line is one the goes straight up and down parallel to the y axis of the coordinate plane.
Horizontal and vertical lines 1 cool math has free online cool math lessons cool math games and fun math activities.
Vertical angles vertical angles are different use of the word vertical.
The vertical bar is a glyph with various uses in mathematics computing and typography it has many names often related to particular meanings.
In the figure above drag either point and note that the line is vertical when they both have the same x coordinate.
