Answer:
The midpoint is (1.29,-1.35)
Explanation:
To find the x coordinate of the midpoint, average the x coordinates of the endpoints
(3.1+-.52)/2 =2.58/2=1.29
To find the y coordinate of the midpoint, average the y coordinates of the endpoints
(-2.1+-.6)/2 =-2.7/2=-1.35
The midpoint is (1.29,-1.35)
