Line slope diagram

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