What Is Segment Addition Postulate?
Segment Addition Postulate computes distance, midpoint, and slope between two points in the coordinate plane.
Formula
d = √((x₂−x₁)² + (y₂−y₁)²), midpoint = ((x₁+x₂)/2, (y₁+y₂)/2), slope = (y₂−y₁)/(x₂−x₁)Frequently Asked Questions
What if the line is vertical?
A vertical line has an undefined (infinite) slope because x₂ − x₁ = 0.
