# Line slope calculator

Slope calculator finds the slope of a line, parametric, normal, and slope y-intercept equation of a line given by coordinates of two points A, B in a plane. The slope formula is sometimes referred to as "rise over run". slope = rise/run. The calculator will calculate the slope by finding the ratio of the "vertical change" (dy) to the "horizontal change" (dx) between two distinct points A, B on a line. The slope is quotient "rise over run". The horizontal line slope is zero, and the vertical line slope is undefined (infinity).

$m={\displaystyle \frac{dy}{dx}}={\displaystyle \frac{\mathrm{\Delta}y}{\mathrm{\Delta}x}}={\displaystyle \frac{{y}_{1}-{y}_{0}}{{x}_{1}-{x}_{0}}}$
