Slope Formula

The slope of a line between two points (x₁, y₁) and (x₂, y₂) is:

m = \\frac{y_2 - y_1}{x_2 - x_1} = \\frac{\\text{rise}}{\\text{run}}

The slope represents the rate of change: how much y changes for each unit change in x.

Special Cases

Positive slope: Line rises from left to right

Negative slope: Line falls from left to right

Zero slope: Horizontal line (y = constant)

Undefined slope: Vertical line (x = constant)
