Slope Calculator

Calculate the slope of a line between two points with step-by-step solutions

Point Coordinates

Point 1 (x₁, y₁)

Current: (1, 2)

Point 2 (x₂, y₂)

Current: (4, 8)

Formula

m = (y₂ - y₁) / (x₂ - x₁)

where m is the slope

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

Road grade/incline
