Midpoint of the points (-1, 4) and (3, -1)

Given Coordinates: x1 = -1  y1 = 4,  x2 = 3  y2 = -1
Midpoint Formula: midpoint = ( 
x1 + x2/2
 ,  
y1 + y2/2
 )
Substitute the given coordinates into the Midpoint Formula and Simplify:
midpoint = ( 
-1 + 3/2
 ,  
4 + (-1)/2
 )
midpoint = ( 
-1 + 3/2
 ,  
4 − 1/2
 )
midpoint = ( 
2/2
 ,  
3/2
 )
midpoint = (1,  
3/2
 )
midpoint = (1, 1.5)
Therefore, (1, 1.5) is the midpoint of the points (-1, 4) and (3, -1)
