## Is a horizontal line positive or negative?

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.

y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e.

x1 − x2 = 0)..

## What is the 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.

## What is the equation of the horizontal line (- 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 happens when you apply the slope formula to a horizontal line?

Zero! This relationship always holds: a slope of zero means that the line is horizontal, and a horizontal line means you’ll get a slope of zero.

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

Answer: y-9 = 0 ( or ) y= 9 is the correct equation. where m = slope of the line passing through . thus you got the answer.

## What is the slope of a horizontal line?

Slope of a horizontal line. When two points have the same y-value, it means they lie on a horizontal line. The slope of such a line is 0, and you will also find this by using the slope formula.

## What does a straight horizontal line on a graph mean?

Speed or velocity is plotted on the Y-axis. A straight horizontal line on a speed-time graph means that speed is constant. It is not changing over time. A straight line does not mean that the object is not moving!

## How do you find the horizontal change?

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.

## Why do we use the horizontal line test?

The horizontal line test is a convenient method that can determine whether a given function has an inverse, but more importantly to find out if the inverse is also a function.

## What does a horizontal line look like?

In geometry, a horizontal line is one which runs from left to right across the page. It comes from the word ‘horizon’, in the sense that horizontal lines are parallel to the horizon. … A vertical line is perpendicular to a horizontal line. (See perpendicular lines).

## 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).

## How do you tell if a line is vertical or horizontal?

Note that when a line has a positive slope it rises up left to right. Note that when a line has a negative slope it falls left to right. Note that when a line is horizontal the slope is 0. Note that when the line is vertical the slope is undefined.
