We can define distance as either a measure of the space between two things or how far one thing is from another thing.
The only difference between distance and displacement is that, displacement is direction sensitive.
To determine the distance between two point, we must know how to read coordinates of a point and interpret it in terms of x axis and y axis.
Formula to calculate distance between two points.
Lets take the points (3,2) and (7,8).
( 3,2 ) = ( x,y ) of the first point.
( 7,8 ) = ( x,y ) of the second point.
Therefore, the distance between the two points is 7.211 units.
