## 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.

All you need to do is remember these..

## What is the function of a horizontal line?

A horizontal line is a function. This is because every x value corresponds to only one y value ( kind of like one input only has one output ).

## How do you tell if a graph is horizontally stretched or compressed?

If a > 1 \displaystyle a>1 a>1, then the graph will be stretched.If 0 < a < 1, then the graph will be compressed.If a < 0 \displaystyle a<0 a<0, then there will be combination of a vertical stretch or compression with reflection.

## What is horizontal line known as?

The horizontal line is a straight line that is mapped from left to right and it is parallel to the X-axis in the plane coordinate system. In other words, the straight line that does not make any intercept on the X-axis and it can have an intercept on Y-axis is called horizontal line.

## How do you determine horizontal and vertical shifts?

The vertical shift results from a constant added to the output. Move the graph up for a positive constant and down for a negative constant. The horizontal shift results from a constant added to the input. Move the graph left for a positive constant and right for a negative constant.

## How do you know if compression is horizontal or vertical?

When we multiply a function by a positive constant, we get a function whose graph is stretched or compressed vertically in relation to the graph of the original function. If the constant is greater than 1, we get a vertical stretch; if the constant is between 0 and 1, we get a vertical compression.

## How do you find a horizontal asymptote?

To find horizontal asymptotes:If the degree (the largest exponent) of the denominator is bigger than the degree of the numerator, the horizontal asymptote is the x-axis (y = 0).If the degree of the numerator is bigger than the denominator, there is no horizontal asymptote.More items…•

## What is an example of a horizontal line?

An equation that only crosses the y-axis is a horizontal line. … For example: y=5 is a horizontal line that crosses the y-axis at (0,5).

## What does a horizontal shift look like?

the horizontal shift is obtained by determining the change being made to the x-value. The horizontal shift is C. The easiest way to determine horizontal shift is to determine by how many units the “starting point” (0,0) of a standard sine curve, y = sin(x), has moved to the right or left.

## How do you do horizontal shift?

A General Note: Horizontal Shift Given a function f, a new function g ( x ) = f ( x − h ) \displaystyle g\left(x\right)=f\left(x-h\right) g(x)=f(x−h), where h is a constant, is a horizontal shift of the function f. If h is positive, the graph will shift right. If h is negative, the graph will shift left.

## What does a vertical shrink look like?

The y -values are being multiplied by a number between 0 and 1 , so they move closer to the x -axis. This tends to make the graph flatter, and is called a vertical shrink. In both cases, a point (a,b) on the graph of y=f(x) y = f ( x ) moves to a point (a,kb) ( a , k b ) on the graph of y=kf(x) y = k f ( x ) .

## Is horizontal side to side or up and down?

The terms vertical and horizontal often describe directions: a vertical line goes up and down, and a horizontal line goes across. You can remember which direction is vertical by the letter, “v,” which points down.

## What is the formula 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. … Graph of a Line Since y always takes the value -1, an equation for the line is y = – 1.

## What is a horizontal shrink?

A horizontal stretch or shrink by a factor of 1/k means that the point (x, y) on the graph of f(x) is transformed to the point (x/k, y) on the graph of g(x). Examples of Horizontal Stretches and Shrinks. Consider the following base functions, (1) f (x) = x2 – 3, (2) g(x) = cos (x).

## What is horizontal line picture?

There’s something about a horizontal line in an image that conveys a message of ‘stability’ or even ‘rest’. … Horizons are the most common horizontal line to be found in photographs and they often act as a dividing point in a photograph – in effect an anchor that the rest of the image is formed around.
