Slope is rise over run: how much a line climbs vertically for each unit it travels horizontally. A slope of 2 rises two units per unit across; a negative slope falls; a slope of 0 is flat. Vertical lines are the one exception — their run is zero, so the slope is undefined. Road grades use the same idea: a 6% grade is simply a slope of 0.06.

Slope Between Two Points

m = \frac{y_2 - y_1}{x_2 - x_1}

Where

$m$ = Slope
$x_1$ = First point x-coordinate
$y_1$ = First point y-coordinate
$x_2$ = Second point x-coordinate
$y_2$ = Second point y-coordinate
