A positive slope means that **two variables are positively related**—that is, when x increases, so does y, and when x decreases, y also decreases. Graphically, a positive slope means that as a line on the line graph moves from left to right, the line rises.

## What is a positive slope example?

In our pizza example, a positive slope tells us that as **the number of toppings we order (x) increases, the total cost of the pizza (y) also increases**. For example, as the number of people that quit smoking (x) increases, the number of people contracting lung cancer (y) decreases.

## What does a negative slope mean?

Visually, a line has negative slope if it goes down and right (or up and left). Mathematically, this means that **as x increases, y decreases.**

## What does negative slope look like?

Graphically, a negative slope means that **as the line on the line graph moves from left to right, the line falls**. We will learn that “price” and “quantity demanded” have a negative relationship; that is, consumers will purchase less when the price is higher. ... Graphically, the line is flat; the rise over run is zero.

## What are 4 types of slopes?

There are four different types of slope. They are **positive, negative, zero, and indefinite**.

### How does a slope look like?

**The slope equals the rise divided by the run:** . You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it. So, you can choose any 2 points along the graph of the line to figure out the slope.

### Why would a slope be 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.

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

Zero Slope and Graphing

Just like in the bicycling example, **a horizontal line goes** with zero slope. One thing to be aware of when you graph, however, is that this horizontal line can be any height. For example, the picture you see here has three horizontal lines. In each case the slope is zero.

### What does a slope of 2 look like?

In other words, our line moves 2 units upward every time it moves 1 unit to the right. Our slope is 2. It's a **positive** number, so we rise up and run to the right. Or, if we want to be contrary, both the rise and run could be negative, moving down and to the left.

### Is the slope always positive?

When calculating the rise of a line's slope, down is always **negative and up is always positive**. When calculating the run of a line's slope, right is always positive and left is always negative.

### How do you know if a slope is zero?

**A horizontal line has slope zero since it does not rise vertically** (i.e. y_{1} − y_{2} = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x_{1} − x_{2} = 0).

### Can there be a slope of 0?

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.

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

If the slope is negative, then **the rise and the run have to be opposites of each other**, one has to be positive and one has to be negative. In other words, you will be going up and to the left OR down and to the right.

### How do you find the slope given two points?

Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is **m=(y2-y1)/(x2-x1)**, or the change in the y values over the change in the x values. The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.

### What is a gentle slope?

adjective. A gentle slope or curve **is not steep or severe**.

### What would be in slope?

The slope of a line characterizes the direction of a line. To find the slope, you **divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points**.

### How do you identify a slope?

**From the previous section, you have discovered that there are four types of slope.**

- postive slope (when lines go uphill from left to right)
- negative slope (when lines go downhill from left to right)
- zero slope (when lines are horizontal)
- undefined slope (when lines are vertical)

### What is standard form slope?

Standard form is another way to write slope-intercept form (as opposed to y=mx+b). It is written as **Ax+By=C**. You can also change slope-intercept form to standard form like this: Y=-3/2x+3. ... A, B, C are integers (positive or negative whole numbers) No fractions nor decimals in standard form. "Ax" term is positive.

### 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**.

### What does a slope of 1 mean?

A slope of 1 means **it rises just as fast as it goes forward**. The slope is at a 45∘ angle. (And a slope of −1 means it sinks just as fast as it goes forward).

### What does a slope of infinity look like?

An infinite slope is simply **a vertical line**. When you plot it on a line graph, an infinite slope is any line which runs parallel to the y-axis. You can also describe this as any line that doesn't move along the x-axis but stays fixed at one constant x-axis coordinate, making the change along the x-axis 0.

### What if the slope has a 0 on top?

When the 0 is on the “top” of the fraction, that would mean that the two y-values are the same. Thus that line is **horizontal** (slope of 0). If the “bottom” of the fraction is 0 that means the two x-values are the same. Thus that line is vertical (undefined slope).

### Can you have a slope of 0 6?

Answer and Explanation: **No, the slope 06 is not undefined**. By definition, an undefined slope is a slope with a 0 in the denominator of the slope.
