Slope Calculator

Posted by Dinesh on

Slope of a Line Calculator is an online tool, that helps to calculate the slope of a line if coordinates of two points are given. This Calculator requires the co-ordinates of two points on the line as (x1, y1) and (x2, y2).

What is Slope?

Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line. Sometimes the ratio is expressed as a quotient ("rise over run"), giving the same number for every two distinct points on the same line.

  • Uphill slopes are positive slopes. The slope will be a positive number like 8 or 6/7.
  • Downhill slopes are negative slopes. The slope will be a negative number like -2 or -7/4.

Slope of a Line Calculation

Slope (m) :


m = (y2 - y1) / (x2 - x1)

x1, x2, y1, y2 - coordinates of two points

Example: Find the slope for co-coordinates (-12, 7) and (-11, -3)

Slope between two points:
m = (y2 - y1) / (x2 - x1)
(x1, y1) = (-12, 7)
(x2, y2) = (-11, -3)
m = (-3 - 7) / (-11 - (-12))
m = -10
