In coordinate geometry a vertical line is parallel to the y axis on the coordinate plane.
Vertical line math equation.
How do you write an equation for a horizontal line.
It is a vertical line.
The slope is undefined.
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.
We often think of a vertical line as being the opposite of a horizontal line.

High school math solutions perpendicular parallel lines calculator.
Remember that vertical lines only have a y value and no x value.
And where does it cross the y axis.
What is the equation for a vertical line.
Vertical lines help determine if a relation is a function in math.
Since the line crosses the x axis at 15 the equation of the line is.
No matter what y is x is equal to negative five.
Follow along with this tutorial as you see how use the information given to write the equation of a horizontal line.
Every point on the line has x coordinate 1 5 that is why its equation is x 1 5.
Trying to find the equation of a horizontal line that goes through a given point.
In fact this is a special case and you use a different equation not y but instead you use x.
Free line equation calculator find the equation of a line given two points a slope or intercept step by step.
And so notice x never changes.
Determine if the line shown in fig 1 is vertical and write its equation.
Its equation is x is equal to negative five.
So a vertical line well that just goes straight up and down.
This has an undefined slope.
Below is the graph of a vertical line that has an x intercept of h 0.

The points a and b on the line are at 15 3 and 15 20.
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 a line that goes straight up and down.
