Distance Between Two Points

Y coordinates are the same:

Example    The coordinates,  x,y  are (4,2) at  point B and (-2,2)  at point A. 

Subtract the X coordinates to find the distance between the 2 points.

   4 - (-2) = 6  The distance between A and B is 6 units.

X coordinates are the same

Example  The coordinates are (3,3) and 3,-2.

The  X coordinates are the same.  Subtract the Y coordinates to find the distance between the 2 points.

  3 - (-2)  = 5   The Distance between  point c and d is 5 units.

coordinates are different

Example:    The coordinates are (5,4) at point f and (-3,-2) at point e.

Use the distance formula.  See below for the formula.

               2                    2 

   (- 3 - 5)  +  (-2- 4) =   64  +  36  = 100

     square root of 100  = 10 

 The distance between  f and e is 10 units.
