Formula Sheet — Coordinate Geometry

Important formulas and equations from Coordinate Geometry for XAT Quantitative Ability & Data Interpretation.

Formulas — Coordinate Geometry

Basic Coordinate System

Distance = √[(x₂-x₁)² + (y₂-y₁)²]
Midpoint = ((x₁+x₂)/2, (y₁+y₂)/2)

Section Formula

Internal: x = (mx₂+nx₁)/(m+n), y = (my₂+ny₁)/(m+n)
External: x = (mx₂-nx₁)/(m-n), y = (my₂-ny₁)/(m-n)

Straight Line Equations

y = mx + c
Slope = (y₂-y₁)/(x₂-x₁)
ax + by + c = 0
