About the Slope Calculator

Computes the slope of the line through two points, its angle of inclination, and the equation of the line in slope-intercept and general form. Vertical lines, whose slope is undefined, are handled explicitly.

How to use it

Enter two different points.
Press Calculate.
Read the slope and the equation of the line.

Example

(1, 2) and (3, 6)

→ slope 2, line y = 2x

Formulas used

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

Slope: rise over run.

y - y_1 = m(x - x_1)

Point-slope form of the line.
