The Undefined slope graph is a line parallel to the y-axis or perpendicular to the x-axis. Thus there is no y-intercept and there is no change in the x-coordinates.

Jul 23, 2025 · In this article, we will discuss about undefined slope in detail along with the equation for undefined slope and how we can identify the undefined slope in graphs.

Understand the definition of undefined slope and zero slope. Learn how to identify if a slope is undefined, and explore how the graphs for zero slope lines and undefined slope lines look.

Explore the different types of slopes of a line: positive, negative, zero, plus the undefined slope. Understand the basics of a line's steepness expressed as rise over run.

Mar 4, 2025 · An undefined slope means the line moves straight up and down without shifting sideways. This is called a vertical line, where all points share the same x-value while the y-values change.

An undefined slope represents a vertical line on a graph. This occurs because the change in x (run) is zero, leading to division by zero in the slope formula (rise/run), which is undefined in mathematics.

Graphically, an undefined slope is represented by perfectly vertical lines on a graph. For undefined slope example, if we look at lines like `x = -4, x = 2` and `x = 8`, they all show undefined slopes because …

Nov 27, 2025 · An undefined slope is a vertical line, which has no horizontal change, so its slope cannot be calculated. A zero slope, on the other hand, is a horizontal line, which has no vertical change and …

In geometry, an undefined slope, sometimes referred to as an "infinite slope," is a term used to describe a line that has no slope. This means that the line is either vertical or horizontal.

In general, when the x-values or x-coordinates are the same for all points on a line, the slope is undefined. If you can make this observation, there is no need to compute the slope.
