Vertical Line Math Equation

The points a and b on the line are at 15 3 and 15 20.

Vertical line math equation.

Since they are equal the line is vertical. The slope is undefined. Since the line crosses the x axis at 15 the equation of the line is. Improve your math knowledge with free questions in equations of horizontal and vertical lines and thousands of other math skills.

This has an undefined slope. The vertical line also called the vertical slash or upright slash is used in mathematical notation in place of the expression such that or it is true that this symbol is commonly encountered in statements involving logic and sets. And where does it cross the y axis. It is a vertical line.

How do you write an equation for a horizontal line. By using this website you agree to our cookie policy. No matter what y is x is equal to negative five. Trying to find the equation of a horizontal line that goes through a given point.

So it s just going to look like this. Its equation is x is equal to negative five. 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. Follow along with this tutorial as you see how use the information given to write the equation of a horizontal line.

Remember that vertical lines only have a y value and no x value. Every point on the line has x coordinate 1 5 that is why its equation is x 1 5. And so notice x never changes. Vertical lines help determine if a relation is a function in math.

Below is the graph of a vertical line that has an x intercept of h 0. Also see mathematical symbols. Determine if the line shown in fig 1 is vertical and write its equation. The equation of a vertical line always takes the form x k where k is any number and k is also the x intercept.

In fact this is a special case and you use a different equation not y but instead you use x. In coordinate geometry a vertical line is parallel to the y axis on the coordinate plane. We often think of a vertical line as being the opposite of a horizontal line.
