Slope y 2 y 1 x 2 x 1 How it works. Step 1 Calculate the slope from 2 points. Substitute either point into the equation.
Slope calculator uses coordinates of two points AxAyA A x A y A and BxByB B x B y B in the two-dimensional Cartesian coordinate plane and find the slope coefficient of a line that passes through A A and B B.
Slope direction of a line. The other format for straight-line equations is called the point-slope form. Use the equation of rise over run which is Y2-Y1 divided by X2-X1. A line has a constant slope and is horizontal when m 0.
