Determine the midpoint of the two points (1,5)and (8,10).
Enter the answer as an ordered pair, including the comma.
The midpoint is

Answer 1

The midpoint of any two points is the average of the x-coordinate and y-coordinates.  This method is similar to finding the number between two middle numbers when finding the median of a set of numbers.

 

 

Midpoint = ( (x₁ + x₂) / 2 , (y₁ + y₂) / 2 )

          

             = ( (1 + 8) / 2  ,   (5 + 10) / 2 )

    

             = (9/2  ,   15/2)

            

             = (4.5 , 7.5)

 

 

The midpoint is (4.5 , 7.5)
