Straight Lines — Key Formulas
| Formula | Expression |
|---|---|
| Slope of Line | m = (y₂ − y₁)/(x₂ − x₁) |
| Point-Slope Form | y − y₁ = m(x − x₁) |
| Slope-Intercept Form | y = mx + c |
| General Form | ax + by + c = 0 |
| Distance Between Points | d = √((x₂ − x₁)² + (y₂ − y₁)²) |
| Distance Point to Line | d = |ax₀ + by₀ + c|/√(a² + b²) |
| Angle Between Lines | tanθ = |(m₁ − m₂)/(1 + m₁m₂)| |
