## What are the three equations of a line?

There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form.

We review all three in this article.

There are three main forms of linear equations..

## How do you find parallel lines?

Two lines are parallel if the have the same slope. Example 1: Find the slope of the line parallel to the line 4x – 5y = 12. To find the slope of this line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = 12 is m = 4/5.

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

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.

## How do you find the equation of a line that passes through a point?

Find the Equation of a Line Given That You Know a Point on the Line And Its Slope. The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept. If you a point that a line passes through, and its slope, this page will show you how to find the equation of the line.

## What is the equation of a 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 a horizontal line through 6?

Example 2: Write an equation for the horizontal line that passes through (6, 2). Since the line is horizontal, y is constant–that is, y always takes the same value. Since y takes a value of 2 at the point (6, 2), y always takes the value 2. Thus, the equation is y = 2.

## 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 line?

The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept. If you know two points that a line passes through, this page will show you how to find the equation of the line.

## What is the slope intercept form equation of the line that passes through 3 4 and 5/16 )?

What is the slope-intercept form equation of the line that passes through (3, 4) and (5, 16)? y = 6x − 14.

## 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 equation of a straight line?

The general equation of a straight line is y = m x + c , where is the gradient and the coordinates of the y-intercept.

## 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 is the equation of a vertical line passing through the point (- 4 7?

Note − The equation of a vertical line is always of the type x=k and hence the equation of the vertical line passing through (4,7) is x=4 .
