vertical line A line with an undefined slope is, by definition, a vertical line. Therefore, for each and every value of y , the value for x will be the same. Therefore, any two points on a line with an undefined slope will have their x values in common.
Why does a horizontal line have a slope of 0 but a vertical line has an undefined slope?
Answer: The slope of a vertical line. A vertical line has undefined slope because all points on the line have the same x-coordinate. As a result the formula used for slope has a denominator of 0, which makes the slope undefined. A horizontal line has slope 0 because all its points have the same y-coordinate.
Can a line have an undefined slope?
Any vertical line, like the one shown below, will have an undefined slope. These lines are always of the form x=c, where c is some number. To understand the discussion below, you should be familiar with finding the slope using the slope formula.

What is undefined slope?
An undefined slope (or an infinitely large slope) is the slope of a vertical line! The x-coordinate never changes no matter what the y-coordinate is! There is no run! In this tutorial, learn about the meaning of undefined slope.
What is the slope of any horizontal line?
The slope of a horizontal line is zero while the slope of a vertical line is undefined.

Do horizontal lines have a slope?
A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0).
What is the horizontal line test used for?
In mathematics, the horizontal line test is a test used to determine whether a function is injective (i.e., one-to-one).
What type of slope does a horizontal line have?
The slope of a line can be positive, negative, zero, or undefined. A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0).
How do I know if a slope is undefined?
Note that when a line has a negative slope it goes down left to right. Note that when a line is horizontal the slope is 0. Note that when the line is vertical the slope is undefined.
Is the slope of a vertical line always undefined?
As a vertical line will always make an angle the size of of 90° with the positive direction of the x -axis. tan ( 90°) = undefined. Flat horizontal lines do have a slope that is defined, the slope is always a value of 0. Neither sloping upward or downward. Both horizontal lines C and D have a slope of 0.
Is the slope of a horizontal line zero or zero?
A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0). Popular Trending
