Vertical Line Math Example

The vertical lines have no slope.

Vertical line math example.

The equation of a vertical line always takes the form x k where k is any number and k is also the x intercept. The vertical line test. A vertical line is one the goes straight up and down parallel to the y axis of the coordinate plane. Movement can also be vertical.

Vertical lines in math. The line has to be vertical as illustrated above. The vertical line test supports the definition of a function. If you think about it the vertical line test is simply a restatement of the definition of a function.

More about vertical line test. Explaining why a vertical line doesn t represent a function. In math the y axis is. 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.

If we say that the motion is vertical it means the direction of movement is top down or bottom up. Some examples are shown below. Are the points of vertical lines. The vertical bar is a glyph with various uses in mathematics computing and typography it has many names often related to particular meanings.

Examples of vertical line test. Vertical line test is generally done by using a ruler. Using vertical line test the graph given represents a function as the vertical line drawn intersects the graph at only one point. Next we show you a few examples where the vertical line test was used to determine if the graph is a function.

In the figure above drag either point and note that the line is vertical when they both have the same x coordinate. Vertical lines help determine if a relation is a function in math. That is every x value of a function must be paired to a single y value. States that if a vertical line intersects the graph of the relation more than once then the relation is a not a function.

Some examples showing how to use the vertical line test to check if a relation is a function or not. 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. If you re seeing this message it means we re having trouble loading external resources on our website. Is a way to determine if a relation is a function.

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. For example 2 0 3 0 4 0 etc. Similarly the line which goes from left to right and is parallel to the x axis is called a horizontal line. All points on the line will have the same x coordinate.
