The distance between points (x₁,y₁) and (x₂,y₂) is d = √((x₂−x₁)²+(y₂−y₁)²). In 3D: d = √((x₂−x₁)²+(y₂−y₁)²+(z₂−z₁)²). Manhattan distance |x₂−x₁|+|y₂−y₁| measures grid-based travel. The midpoint is ((x₁+x₂)/2, (y₁+y₂)/2).
How to Use
Enter two points:
- 2D: (x₁,y₁) and (x₂,y₂)
- 3D: Add z coordinates
- Results: Distance, midpoint, slope
Distance Formulas
- Euclidean: √(Σ(xᵢ−yᵢ)²)
- Manhattan: Σ|xᵢ−yᵢ|
- Chebyshev: max|xᵢ−yᵢ|
Line Equation
Slope m = (y₂−y₁)/(x₂−x₁). Point-slope: y−y₁ = m(x−x₁). Slope-intercept: y = mx + b.
