# How do you translate a linear function horizontally?

Space and Astronomyhorizontal movement will ALWAYS be inside with the x added or subtracted and is OPPOSITE what you want. To move the function horizontally, **place the number inside parenthesis and do the opposite of the way you want to move**. To move left put a plus and your number and to move right put a minus and your number.

## Can a linear function be horizontal?

A linear function can have none, one, or infinitely many zeros. **If the function is a horizontal line ( slope = 0 ), it will have no zeros unless its equation is y=0 , in which case it will have infinitely many**. If the line is non-horizontal, it will have one zero.

## How do you shift a function horizontally?

You make horizontal changes by **adding a number to or subtracting a number from the input variable x, or by multiplying x by some number**. All horizontal transformations, except reflection, work the opposite way you’d expect: Adding to x makes the function go left. Subtracting from x makes the function go right.

## How do you horizontally stretch a linear function?

Video quote: *And if I'm horizontally stretching by a factor of 2 I take the x coordinates. Though again remember horizontal. So I take the x coordinates.*

## How do you translate a linear function?

**When the y-intercept b is changed in the function f(x) = mx + b, the graph is translated vertically**. If b increases, the graph is translated up. If b decreases, the graph is translated down.

## What function is a straight horizontal line?

HORIZONTAL LINES – **CONSTANT FUNCTIONS**

Horizontal lines are the graphs of constant functions, those whose values never change no matter what values are acted upon. Any x value produces the same y value as that of all the other x values: the result is constantly the same. The slope of a horizontal line is zero.

## What is the linear equation for a horizontal line?

Horizontal lines have a slope of 0. Thus, in the slope-intercept equation y = mx + b, m = 0. The equation becomes **y = b**, where b is the y-coordinate of the y-intercept.

## How do you write a horizontal equation?

Video quote: *3 so for horizontal lines your Y coordinates consistent your equation is going to be y equals a constant and for your vertical lines the x coordinate is gonna be the one that's constant.*

## How is horizontal?

**Anything parallel to the horizon** is called horizontal. As vertical is the opposite of horizontal, anything that makes a 90-degree angle (right angle) with the horizontal or the horizon is called vertical. So, the horizontal line is one that runs across from left to right.

What is Horizontal?

Horizontal | Vertical |
---|---|

24 + 33 = 57 | 24 + 33 = 57 |

## Is Y =- 5 a horizontal line?

The graph of a relation of the form y = 5 is **a line parallel to the x-axis** because the y value never changes.

## Is Z horizontal or vertical?

vertical

The coordinate surfaces of the Cartesian coordinates (x, y, z). **The z-axis is vertical** and the x-axis is highlighted in green.

## How do you tell if an equation is horizontal or vertical?

**We learned:**

- Horizontal lines go side to side and have a slope of 0.
- Vertical lines go up and down and have a slope that is undefined.
- Graphs of horizontal lines are parallel to the x-axis.
- Graphs of vertical lines are parallel to the y-axis.

## What is the horizontal line through (- 4 6?

In a horizontal line the y value remains the same. In the point ( -4. -6 ) the y value is **-6**. the point notation is always written as ( x, y).

## What is the equation of the horizontal line through 1 9 )?

What is the equation of a horizontal line that goes through the point 1 9? Answer: **y-9 = 0** ( or ) y= 9 is the correct equation.

## What is the equation of the horizontal line through 5 7?

Explanation: The point (a,b) is (5,7) . Therefore, the equation of the line is **y=7** .

## What is the equation of the horizontal line through 2 3?

The horizontal line 1 passing through the point (2, -3) is represented by the equation **y = -3**.

## How do you write an equation for a vertical and horizontal line?

Horizontal lines go left and right and are in the form of y = b, where b represents the y-intercept, while vertical lines go up and down and are in the form of x = a where a represents the shared x-coordinate of all points.

## Is the intercept of the horizontal line which passes through 2 − 3?

Explanation: Any horizontal line parallel to the x-axis has a zero slope. The horizontal line passing through (-2 ,3) has equation **y = 3** as it passes through all points in the plane with a y-coordinate of 3, as may be seen in the graph.

## How do you graph horizontal and vertical lines?

Video quote: *Line now this might make a little bit more sense if you learn about the slope intercept form of the line the y equals MX plus B form of the line because.*

## How does a horizontal line look?

A horizontal line is **a straight line that goes from left to right or right to left**. In coordinate geometry, a line is said to be horizontal if two points on the line have the same Y- coordinate points. It comes from the term “horizon”. It means that the horizontal lines are always parallel to the horizon or the x-axis.

## Which way is horizontally?

The terms vertical and horizontal often describe directions: a vertical line goes up and down, and a horizontal line **goes across**.

## How do you graph a horizontal line?

To graph a horizontal line that goes through a given point, **first plot that point.** **Then draw a straight line left and right that goes through the point**, and you’re done!

## What is an example of horizontal?

The definition of horizontal is something that is parallel to the horizon (the area where the sky seems to meet the earth). An example of a horizontal line is **one that goes across the paper**.

## What does horizontally mean?

**at right angles to the vertical; parallel to level ground**. flat or level: a horizontal position. being in a prone or supine position; recumbent: His bad back has kept him horizontal for a week. near, on, or parallel to the horizon.

## What is horizontal shape?

**Straight lines are horizontal if they go across from side to side, without going up or down at all**. Straight lines are vertical if they go straight up and down, or top to bottom, without going across at all. Lines are slanting if they don’t go straight across or straight up.
