1. Algebra I – Linear Equations & Inequalities
Linear equations form the foundation of algebra. These formulas help you work with straight lines, slopes, and systems of equations. Master these first!
| Topic | Formula | Description |
|---|---|---|
| Slope-Intercept Form | y = mx + b | m = slope, b = y-intercept |
| Point-Slope Form | y – y₁ = m(x – x₁) | Line through point (x₁, y₁) with slope m |
| Standard Form | Ax + By = C | A, B, C are constants |
| Slope Formula | m = (y₂ – y₁)/(x₂ – x₁) | Slope between two points (rise over run) |
| Parallel Lines | m₁ = m₂ | Same slope means parallel |
| Perpendicular Lines | m₁ × m₂ = -1 | Negative reciprocal slopes |

💡 Quick Tip: When two lines are perpendicular, their slopes multiply to give -1. For example, if one line has slope 2, the perpendicular line has slope -1/2.
2. Algebra II – Quadratics & Polynomials
