Answer:

The midpoint  of AB = (1,0)

Step-by-step explanation:

Explanation:-

Given that  points A( 3,1) and B(-1,-1)

Midpoint rule

     =   [tex](\frac{x_{1} +x_{2} }{2} ,\frac{y_{1}+y_{2} }{2} )[/tex]

Let 'D' be the midpoint

  [tex]D = ( \frac{3-1}{2} ,\frac{1-1}{2} )[/tex]

  [tex]D = ( \frac{2}{2} ,\frac{0}{2} )[/tex]

  D = (1,0)

The midpoint  of AB = (1,0)
