What to Study
- The coordinate plane
- Finding slope
- Graphing lines
- Slope-intercept form (y = mx + b)
- Point-slope form
- Standard form
- Writing linear equations
- Parallel and perpendicular lines
Key Formulas
Slope = (y₂ - y₁) / (x₂ - x₁)
Slope-intercept: y = mx + b
Point-slope: y - y₁ = m(x - x₁)
Parallel lines: same slope
Perpendicular lines: slopes are negative reciprocals
