## What Is Positive Slope?

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

## What is an example of a positive slope?

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.

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

## How do you know if a slope is positive or negative?

A **higher positive slope** means a steeper upward tilt to the curve which you can see at higher output levels. A negative slope that is larger in absolute value (that is more negative) means a steeper downward tilt to the line. A slope of zero is a horizontal line.

## What does 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.**

## Which describes a line that has a positive slope?

A line has a positive slope **if it is slanting upward toward the right**. A line has a negative slope if it is slanting upward toward the left.

## What are 4 types of slopes?

**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)

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

## What are the difference between positive and negative slope zero and undefined slope?

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. 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). because division by zero is an undefined operation.

## Why is it called intercept form?

One form of the equation of a straight line is called the slope-intercept form **because it contains information about these two properties**. In the equation y = mx + c the value of m is called the slope (or gradient) of the line. … Lines with a zero gradient are horizontal.

## What is negative slope and positive slope?

**steeper downward tilt to the line**. … A vertical line has an infinite slope.

## What do you do when the slope is negative?

**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.

## What do you do when y is negative?

## Is the slope always positive?

**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. … We can choose any two points on the line and will come up with the same slope.

## What is a zero slope?

**is perfectly flat in the horizontal direction**. The equation of a line with zero slope will not have an x in it.

## How do you make a slope positive?

**y always increases when x increases and y always decreases when x decreases**. Thus the graph of the line starts at the bottom left and goes towards the top right.

## What are 3 different names for slope?

**Synonyms & Antonyms of slope**

- cant
- diagonal
- grade
- gradient
- inclination
- incline
- lean
- pitch

## Is the slope Positive Negative zero or undefined?

## What are the three types of slope?

**positive negative and zero slopes**.

## What is the difference between zero slope and undefined slope?

1.An undefined slope is characterized by a vertical line while a zero slope has a horizontal line. … The undefined slope has a zero as the denominator while the zero slope has a **difference of zero as a numerator**.

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

An Undefined Slope is **determined by the variable “X”**. A Zero Slope is determined by the variable “Y”. An Undefined Slope has zero as its denominator. A Zero Slope has zero as a difference between its numerators.

## Is 1 an undefined slope?

## What is vertex form?

The vertex form of an equation is **an alternate way of writing out the equation of a parabola**. … From this form it’s easy enough to find the roots of the equation (where the parabola hits the x -axis) by setting the equation equal to zero (or using the quadratic formula).

## What is a vertex from?

**The common endpoint of two or more rays or line segments**. Vertex typically means a corner or a point where lines meet. For example a square has four corners each is called a vertex. The plural form of vertex is vertices. (Pronounced: “ver – tiss- ease”).

## What is linear in math?

**y = mx + b**. Linear relationships are fairly common in daily life.

## What is ay intercept?

**the point where the graph crosses the y -axis**. … When the equation of a line is written in slope-intercept form ( y=mx+b ) the y -intercept b can be read immediately from the equation. Example 1: The graph of y=34x−2 has its y -intercept at −2 .

## Where is the negative and positive on a graph?

**where the function is below the x-axis**. It is where the y-values are negative (not zero).

## How do you graph a negative and positive slope?

## Where is the graph positive?

## How do you write y MX B with a negative B?

## Which expression is equivalent to f/g )( 4 )?

Answer: The Expression **(f + g)(4)** is equal to f(4) + g(4).

## Can you have a negative B in Y MX B?

No the y in slope-intercept form equation **cannot be negative**. By definition the slope-intercept form of a line is y = mx + b.

## Does negative correlation mean negative slope?

In statistics a graph with a negative slope represents a negative correlation between two variables. This means that as **one variable increases the other decreases and vice versa**.

## What is an undefined slope example?

**an elevator**since an elevator can only move straight up or straight down. It got its name “undefined” from the fact that it is impossible to divide by zero. … In general when the x-values or x-coordinates are the same for both points the slope is undefined.
