A vertical line is drawn across the edge of the ruler from one end of the x axis to the other end.
Vertical line math example.
If you think about it the vertical line test is simply a restatement of the definition of a function.
Using vertical line test the graph given represents a function as the vertical line drawn intersects the graph at only one point.
Examples of vertical line test.
In the figure above drag either point and note that the line is vertical when they both have the same x coordinate.
More about vertical line test.
In math the y axis is.
The vertical bar is a glyph with various uses in mathematics computing and typography it has many names often related to particular meanings.
Some examples are shown below.
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.
Are the points of vertical lines.
Similarly the line which goes from left to right and is parallel to the x axis is called a horizontal line.
Vertical lines help determine if a relation is a function in math.
The line has to be vertical as illustrated above.
Some examples showing how to use the vertical line test to check if a relation is a function or not.
The vertical line test.
That is every x value of a function must be paired to a single y value.
Movement can also be vertical.
For example 2 0 3 0 4 0 etc.
The vertical line test supports the definition of a function.

Is a way to determine if a relation is a function.
The equation of a vertical line always takes the form x k where k is any number and k is also the x intercept.
Vertical line test is generally done by using a ruler.
Vertical lines or objects are always perpendicular to the horizontal lines or objects.
You will see a correct vertical line test and an incorrect vertical line test.
Vertical lines in math.
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.
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.
A vertical line is one the goes straight up and down parallel to the y axis of the coordinate plane.
States that if a vertical line intersects the graph of the relation more than once then the relation is a not a function.
Next we show you a few examples where the vertical line test was used to determine if the graph is a function.
The vertical lines have no slope.
