How to use Algebra to find parallel and perpendicular lines. How do we know when two lines are parallel? Their slopes are the same!

In this helpful video, we’ll walk you through the simple steps to determine the slope of a perpendicular line without confusion.

Slope of a perpendicular line can be computed from the slope of a given line. The product of the slope of a given line and the slope of the perpendicular line is equal to -1. If the slope of a line …

Oct 24, 2025 · Determine the slope of the given line, then take the opposite reciprocal of that slop to find the slope of the perpendicular line. You can plug in one given point into the equation y = …

Jan 11, 2023 · Learn how to find the perpendicular slope. When two lines intersect at right angles, they are perpendicular lines, and we can measure their slope.

Perpendicular lines have slopes that are opposite reciprocals of each other. To find the slope of a line that is perpendicular to a given equation, find the opposite reciprocal of that slope.

Enter a point and the slope of a given line to find the perpendicular slope and equation. Perfect for geometry and math problem-solving.

To find the slope of a line perpendicular to another, you take the negative reciprocal of the original line's slope. Identify the slope of the original line. Let's say it's m. Find the negative reciprocal …
