Midpoint of the points (1, 1) and (3, 5)

Given Coordinates: x1 = 1  y1 = 1,  x2 = 3  y2 = 5
Midpoint Formula: midpoint = ( 
x1 + x2/2
 ,  
y1 + y2/2
 )
Substitute the given coordinates into the Midpoint Formula and Simplify:
midpoint = ( 
1 + 3/2
 ,  
1 + 5/2
 )
midpoint = ( 
4/2
 ,  
6/2
 )
midpoint = (2, 3)
Therefore, (2, 3) is the midpoint of the points (1, 1) and (3, 5)
