## What is the Y intercept of a vertical line?

A vertical line (other than x = 0) will not have a y-intercept.

The line x = 0 is another special case since x = 0 is the equation of the y-axis..

## What is the equation for a 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 slope of a diagonal line?

Lines that fall from left to right have a negative slope. So a diagonal line to the right ( / ) would have a positive slope. A diagonal line to the left ( \ ) would have a negative slope. A vertical line ( | )has an undefined slope and a horizontal line ( —- ) has a slope of 0.

## What is an example of a vertical line?

It is a straight line which goes from top to bottom and bottom to top. Any point in this line will have the same value for the x-coordinate. For example, (2,0), (3,0) (-4,0), etc. are the points of vertical lines.

## What is a vertical slope?

Vertical lines have undefined slope. Since any two points on a vertical line have the same x-coordinate, slope cannot be computed as a finite number according to the formula, because division by zero is an undefined operation.

## How do you find the slope of a vertical line?

The slope of a vertical line does not exist! We can’t divide by zero, which is of course why this slope value is “undefined”. This relationship is always true: a vertical line will have no slope, and “the slope is undefined” or “the line has no slope” means that the line is vertical.

## Is Y 2 horizontal or vertical?

Since it’s always hard to remember when these guys are horizontal and when they are vertical, I’ve got a sentence that will always save you… When you see y = -2, say this: y is always -2 and x can be anything! This tells you what the graph should look like!

## How do you tell if a slope 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.

## What is the slope of the line is horizontal?

Horizontal Lines A horizontal line is a line whose equation is of the form =, where is a real number. All points that lie on the line have a -coordinate of . The slope of any horizontal line is zero, 0.

## What is the equation of a vertical line through (- 5 2?

Any vertical line has the equation x = k, where k is the x-coordinate of any point the line goes through. x = -5.

## 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.

## Is a vertical line a function?

For a relation to be a function, use the Vertical Line Test: Draw a vertical line anywhere on the graph, and if it never hits the graph more than once, it is a function. If your vertical line hits twice or more, it’s not a function.
