Line slope calculator

Enter coordinates of two different points:

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).
