Slope Formula
m = (y₂ − y₁) / (x₂ − x₁)
Types of Slope
- Positive slope: Line rises left to right
- Negative slope: Line falls left to right
- Zero slope: Horizontal line (m = 0)
- Undefined slope: Vertical line
Equation Forms
- Slope-intercept: y = mx + b
- Point-slope: y − y₁ = m(x − x₁)
- Standard: Ax + By = C
