Slope Interpretation
Slope Values
m > 0: Line rises (positive)
m < 0: Line falls (negative)
m = 0: Horizontal line
m = undefined: Vertical line
Steepness
|m| = 1: 45° angle
|m| > 1: Steep line
|m| < 1: Gentle line
|m| → ∞: Nearly vertical
Applications
Rate of change
Parallel lines: same slope
Perpendicular: slopes multiply to -1
