Coordinates in the cartesian plane very well have distances from each other. Therefore, some innovative mathematicians derived the distance formula in order to easily calculate the distance of two points in the plane. The distance formula is:
[tex]d= \sqrt{( x_{1}- x_{2} )^{2}+( y_{1}- y_{2} )^{2} } [/tex]
I hope I was able to answer your question. Have a good day.
