## What is an undefined slope called?

Note: 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.

**How do you label an undefined slope?**

An undefined slope indicates that we have a vertical line parallel to the y-axis and passing through all points in the plane with an x-coordinate = constant ( c) The equation is written in the form x = c. In this case the line passes through (-2 ,-6) and therefore the constant is the value of the x-coordinate.

**How do you know when a slope is undefined?**

Note that when a line has a positive slope it goes up left to right. 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.

### Which graph has an undefined slope?

Vertical lines

Vertical lines have an undefined slope, and they’re written in the form x = ___. Horizontal lines have a slope of 0, and they’re written in the form y = ___.

**Is the slope of Y 4 undefined?**

The concept of slope simply does not work for vertical lines. The slope of a vertical line does not exist! We can’t divide by zero, which is of course why this slope value is “undefined”. (By the way, all vertical lines are of the form “x = some number”, and “x = some number” means the line is vertical.

**Can you graph a line if its slope is undefined?**

Yes, the graph of a line with a slope of 0 is a vertical line.

#### What is a straight slope called?

The slope of a straight line is an indication of its steepness of inclination. It is also called the gradient. The steeper a line is, the greater is it slope. The slope of a line stays the same all along its length – that is why the line is straight.

**Is 0 over undefined?**

We can say, zero over zero equals x. Just say that it equals “undefined.” In summary with all of this, we can say that zero over 1 equals zero. We can say that zero over zero equals “undefined.” And of course, last but not least, that we’re a lot of times faced with, is 1 divided by zero, which is still undefined.

**Is the slope of the line in the middle undefined?**

m = 3/0 Since there exist no number you can multiply 0 by to get 3, we say that the slope is undefined. Notice that for the line in the middle, the x-values are the same for both points (x 1 = x 2 = 1). This is also the case for all the lines above.

## Is the slope formula always an undefined formula?

Therefore, the slope formula will always result in division by zero and therefore the slope will be undefined.

**What does undefined look like?**

Basically, a slope that is undefined looks like the lines below: All you do is moving straight up or straight down only. You are not moving horizontally at all. In other words, the run is zero. The slope is therefore at its steepest.

**Which is the correct formula for the slope of a line?**

Therefore, the slope formula will always result in division by zero and therefore the slope will be undefined. We have seen how the slope of a line may be undefined. The other possibilities when calculating the slope are: Negative slope – the line falls from left to right. Positive slope – the line rises from left to right.
