Calculator Use

Calculate the distance between 2 points in a two-dimensional plane.

Enter 2 points as x-y coordinates in the Cartesian coordinate system. Enter (x1, y1) and (x2, y2) to get the distance formula calculation in the 2D plane and find the distance between the 2 points.

Accepts positive or negative numbers, fractions, mixed fractions and decimals.

The calculator answer shows the work for:

  • Distance formula using square root of (x2 - x1) + (y2 - y1)
  • Graph of the line segment connecting the two points
  • Below the graph find a link to the Slope Calculator for the same two points

Distance Formula:

The distance between two points is the length of the line connecting them, and the shortest distance is a straight line.

In a 2 dimensional plane, the distance between points (x1, y1) and (x2, y2) is given by the Pythagorean theorem:

\( d = \sqrt {(x_{2} - x_{1})^2 + (y_{2} - y_{1})^2} \)

Calculate Distance

To calculate the distance between 2 points, (x1, y1) and (x2, y2), for example, (5, 6) and (-7,11), plug the values into the distance formula:

\( d = \sqrt {(-7 - 5)^2 + (11 - 6)^2} \)

combining terms inside parentheses you get:

\( d = \sqrt {(-12)^2 + (5)^2} \)

squaring both terms you get,

\( d = \sqrt {144 + 25} \)

adding the 2 results,

\( d = \sqrt {169} \)

finally,

\( d = 13 \)
