Question 1

What is a Perpendicular Slope?

Accepted Answer

Two lines are perpendicular if they meet at right angles (90°). The slope of a line perpendicular to a line with slope m is −1/m. This is used in geometry, navigation, and engineering.

Question 2

How does the Perpendicular Slope work?

Accepted Answer

If slope of line 1 is m, perpendicular slope = −1/m Then: Product of perpendicular slopes = −1 Then: Horizontal line (m=0) ⊥ vertical line (undefined slope) Then: Two non-vertical lines are perpendicular iff m₁ × m₂ = −1.

Question 3

Can you give an example of how to use the Perpendicular Slope?

Accepted Answer

Example: Input m = 2 gives a result of Perpendicular slope = −½.
