Formula: Slope: m = (y2 - y1) / (x2 - x1). Y-intercept: b = y1 - m*x1. Distance: d = √((x2-x1)² + (y2-y1)²). Angle: θ = atan(m) * (180/π).

In-Depth Guide & Mathematical Methodology

📈 Line Equation Forms & Properties

Slope-Intercept Form: y = mx + b (m = slope, b = y-intercept).

Point-Slope Form: y - y₁ = m(x - x₁).

Parallel Lines: Have equal slopes (m₁ = m₂).

Perpendicular Lines: Slopes are negative reciprocals (m₁ · m₂ = -1).
