What are the coordinates of the midpoint of the segment joining each pair of points.
:(-1, -1), (-8, -9)


Sagot :

Coordinate of the midpoint = (x1 + x2 , y1 + y2)
                                               2            2

midpoint = (-1 + -8  ,  -1 + -9)
                    2              2

midpoint = (-9/2,   -10/2)

Midpoint = (-9/2,  -5)   FINAL ANSWER
