## What must be true about the slopes of two perpendicular lines neither of which is vertical Brainly?

What must be true about the slopes of two perpendicular lines, neither of which is vertical? The slopes are equal.

## What must be true about the slopes of two lines that are perpendicular?

For lines to be perpendicular, the slopes need to be negative reciprocals of each other. For the line, the slope is 1. For a line to be perpendicular to it, it will need to have a slope of. Since the line has a slope of -1, the lines are perpendicular to each other.

## What is the product of the slopes of two non vertical perpendicular lines?

The product of the slopes of two non – vertical perpendicular lines is always -1. It is NOT possible for two perpendicular lines to both have a positive slope because the product of two positives is positive. So for the product of the slopes to be -1, one of the slopes must be positive and the other negative.

## What do you know about the slopes of perpendicular lines?

Perpendicular lines are lines that intersect at right angles. That is, the slopes of perpendicular lines are opposite reciprocals. (Exception: Horizontal and vertical lines are perpendicular, though you can’t multiply their slopes, since the slope of a vertical line is undefined.)

## What is true about the run of all vertical lines?

Verdict: vertical lines have NO SLOPE. 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. (By the way, all vertical lines are of the form “x = some number”, and “x = some number” means the line is vertical.

## How can the coordinates of two points on a line tell you if the line is horizontal or vertical?

If two points share the same x- coordinate, they are vertically separated. They lie on the same vertical line. And if two points share the same y- coordinate, then they are horizontally separated.

## What is a Nonvertical line?

If lines are parallel, they slant in exactly the same direction. Theorem 104: If two lines have the same slope, then the lines are nonvertical parallel lines. If two lines are perpendicular and neither one is vertical, then one of the lines has a positive slope, and the other has a negative slope.

## Can two lines with positive slopes be perpendicular?

is not possible for two lines with positive slopes to be perpendicular to each other.

## When two lines are parallel their slopes are?

In other words, the slopes of parallel lines are equal. Note that two lines are parallel if their slopes are equal and they have different y-intercepts. In other words, perpendicular slopes are negative reciprocals of each other.

## What are the three examples of parallel lines?

In real life, while railroad tracks, the edges of sidewalks, and the markings on streets are all parallel, the tracks, sidewalks, and streets go up and down hills and around curves. Those three real-life examples are good, but not perfect, models of parallel lines. Consider railroad tracks.

## Which of the following is an example of perpendicular lines?

Perpendicular lines occur anytime two lines meet at a 90° angle, also known as a right angle. Sometimes, you will see a little square in the corner of an angle, to show it is perpendicular. There are many examples of perpendicular lines in everyday life, including a football field and train tracks.

## What are two lines that are perpendicular?

If two non-vertical lines in the same plane intersect at a right angle then they are said to be perpendicular. Horizontal and vertical lines are perpendicular to each other i.e. the axes of the coordinate plane. The slopes of two perpendicular lines are negative reciprocals.

## How do you determine if two lines are parallel?

We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect.

## What is the equation of perpendicular lines?

Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6. Rearranged, it is –x/2 + y = 6.

## When two lines are parallel what is the solution?

Lines in a plane that are parallel, do not intersect. Two lines are parallel if they have the same slope, or if they are vertical. If two parallel lines form a system, there are no solutions to the system. If lines intersect, the lines cross in one point.
