What is the relationship between slope and perpendicular lines?
What is the relationship between the slopes of perpendicular lines? Perpendicular lines are lines that intersect at right angles. If you multiply the slopes of two perpendicular lines in the plane, you get −1 . That is, the slopes of perpendicular lines are opposite reciprocals .
Do perpendicular lines have the same exact slope?
Perpendicular lines do not have the same slope. The slopes of perpendicular lines are different from one another in a specific way. The slope of one line is the negative reciprocal of the slope of the other line. The product of a number and its reciprocal is 1. What are perpendicular lines in geometry?
Do perpendicular lines have opposite slopes true or false?
Perpendicular lines have slopes that are flipped and have the opposite sign. It doesn't matter what the y-intercepts are, lines are perpendicular as long their slopes are opposite reciprocals of one another. ... Perpendicular lines have opposite reciprocal slopes.
Which is true of the slopes of parallel lines?
The slopes of parallel lines are equal. The rise and the run will be the same for both lines. Parallel lines are the same distance apart from one another at any given point. If two lines are parallel to a line they are parallel to each other.
How are perpendicular slopes related?
As mentioned above, the slopes of perpendicular lines are negative reciprocals of each other. So, if we know the slope of a line perpendicular to our line, we have it made.
How are the slopes of parallel lines and perpendicular lines related?
The slopes of parallel lines are equal, and the slopes of perpendicular lines are opposite reciprocals. This is a worked example of determining whether given lines are parallel or perpendicular.
Do perpendicular lines have the same slope?
Perpendicular lines do not have the same slope. The slopes of perpendicular lines are different from one another in a specific way. The slope of one line is the negative reciprocal of the slope of the other line.
What is the slope of the perpendicular line?
The slope of a perpendicular line from the slope of a given line is obtained by taking the negative reciprocal of the slope of the given line. If the slope of the given line is m1 and the slope of a perpendicular line is m2 then we have m2 = -1/m1.
What do perpendicular lines have in common?
Perpendicular lines are lines that cross one another at a angle. They have slopes that are opposite reciprocals of one another. Unlike parallel lines. that never touch, perpendicular lines must intersect.
Why slopes of perpendicular lines are negative reciprocals?

What must be true about the slopes of two perpendicular lines?
For lines to be perpendicular, the slopes need to be negative reciprocals of each other.
How do you prove that two lines are perpendicular using slope?
Explanation: If the slopes of two lines can be calculated, an easy way to determine whether they are perpendicular is to multiply their slopes. If the product of the slopes is , then the lines are perpendicular.
How do you find the slope of a line perpendicular two points?

What is the product of the slope of two perpendicular lines?
Perpendicular lines form right angles. If two lines are perpendicular, the slopes are negative reciprocals. (The product of the slopes = -1.)
When two different lines are perpendicular to each other what is the product of their slope?
If you multiply the slopes of two perpendicular lines in the plane, you get −1 . 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.)
How do you find the slope of a line parallel to another line?
First, you should put the equation in slope intercept form (y = mx + b), where m is the slope. The slope of the line is -3/8. A parallel line will have the same slope, thus -3/8 is the correct answer.
