If the endpoints of have the coordinates a(9, 8) and b(-1, -2), what is the midpoint of ab?
a.
(5, 3)
b.
(4, 5)
c.
(5, 5)
d.
(4, 3)

For this case we have that by definition, the formula of the midpoint is given by:

We have the points are:

Option D

answer: yes, he is correct

step-by-step explanation: 10x-1=59

                                              1-1=0     59+1=60

60/10=x=6

d is correct
