The distance between two points of the xy-plane can be calculated using the distance formula.

(x_{1}, y_{1}) (x_{2}, y_{2}) are any two points on the cartesian plane.
**Distance between two points diagram **

Find the distance between the points (-1, 1), (-2, 2).

x_{1} = -1,y _{1} = 1 and x_{2} = -2,y _{2} = 2
Substitute in the formula as

The above example will clearly illustrates how to calculate the Distance between two points manually.
