## How do you write an equation in slope intercept form of a vertical line?

In general, Slope Intercept form is y = mx + b. However, a vertical line has an undefined slope . They also do not have a y-intercept, because they run parallel to the y axis. Therefore, the general formula for a vertical line is x = x1.

## How do you write an equation of a line?

The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.

## What is the equation of a straight vertical line?

The equation of a vertical line always takes the form x = k, where k is any number and k is also the x-intercept . (link) For instance in the graph below, the vertical line has the equation x = 2 As you can see in the picture below, the line goes straight up and down at x = 2.

## What is the equation for vertical line?

Vertical Lines Similarly, in the graph of a vertical line, x only takes one value. Thus, the equation for a vertical line is x = a, where a is the value that x takes. Example 3: Write an equation for the following line: Graph of a Line Since x always takes the value 2 = , the equation for the line is x = .

## What is the equation of a straight horizontal line?

Properties of Horizontal Lines Equation of Horizontal Line always takes the form of y = k where k is the y-intercept of the line. For instance in the graph below, the horizontal line has the equation y = 1 As you can see in the picture below, the line goes perfectly sideways at y =1.

## What is the Y intercept in an equation?

The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis. © 2000-2005 Math.com. All rights reserved.

## How do you turn an equation into a graph?

Divide the difference in y-coordinates by the difference in x-coordinates — 6 ÷ -3 = -2. This is the line’s gradient. Insert the line’s gradient and the y-coordinate from Step 1 as “m” and “c” in the equation “y = mx + c.” With this example, that gives — y = -2x + 8. That’s the equation of the graph.

## What does the equation of a line mean?

Definition: A straight line on the coordinate plane can be described by the equation. y = mx+b. where m is the slope of the line and b is the intercept.

## 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.
