Slope of a Line Calculator

Find the slope from two points: (x1, y1) and (x2, y2). Slope = (y2 − y1) / (x2 − x1).

Point 1: x1, y1

Point 2: x2, y2

Slope calculator

Enter two points (x1, y1) and (x2, y2). The slope is (y2 − y1) / (x2 − x1). If x1 = x2 the line is vertical and the slope is undefined.

Frequently Asked Questions

How do you find the slope of a line?

Slope m = (y2 − y1) / (x2 − x1) for two points (x1, y1) and (x2, y2). Vertical lines have undefined slope.
