Slope Formulas
Slope: m = (y₂ - y₁) / (x₂ - x₁)
Angle: θ = arctan(m)
Distance: d = √[(x₂ - x₁)² + (y₂ - y₁)²]
Special Cases:
- Vertical line: Slope is undefined (x₁ = x₂)
- Horizontal line: Slope is 0 (y₁ = y₂)
- Positive slope: Line rises from left to right
- Negative slope: Line falls from left to right
Note: Calculations are provided as-is for educational and planning purposes. For critical applications, always verify results independently.
