## Is 0 an unidentified slope?

Well you know that having a 0 in the denominator is a big no, no. This means the slope is undefined. As shown above, whenever you have a vertical line your slope is undefined.

**How do you get an unidentified slope?**

If the slope of a line is undefined, then the line is a vertical line, so it cannot be written in slope-intercept form, but it can be written in the form: x=a , where a is a constant. If the line has an undefined slope and passes through the point (2,3) , then the equation of the line is x=2 .

**What happens if the slope is over 0?**

Explanation: An undefined slope occurs when the slope is over 0 .

### What is the value of 1 by 0?

undefined

01 is undefined. Why some people say it’s true: Dividing by 0 is not allowed.

**What does a graph with no slope look like?**

It’s a horizontal line! And just like the horizon, horizontal lines go straight left and right. In this tutorial, you’ll learn all about horizontal lines including their slope and what the equation of a horizontal line looks like.

**What happens when the slope of the line is negative?**

A negative slope means that two variables are negatively related; that is, when x increases, y decreases, and when x decreases, y increases. Graphically, a negative slope means that as the line on the line graph moves from left to right, the line falls.

## Why is the y-intercept always zero?

The Y intercept of a straight line is simply where the line crosses the Y axis. In the above diagram the line crosses the Y axis at 1. The Y intercept is equal to 1 and the point is written as (0,1). Notice that for the y-intercept the x-coordinate of the point is always zero..

**Is infinity an undefined number?**

The value of infinity is also undefined. What is the difference between Infinity and Undefined? Undefined means, it is impossible to solve. Infinity means, it is without bound.

**What letter represents the slope?**

The slope of a line is usually represented by the letter m. (x1, y1) represents the first point whereas (x2, y2) represents the second point.

### What is an example of a zero slope?

When you are graphing lines in mathematics classes, you may also encounter a horizontal line. Just like in the bicycling example, a horizontal line goes with zero slope.
