Answer:
The midpoint is (-3, 1/2)
Explanation:
To find the x coordinate of the midpoint, add the x coordinates of the endpoint and divide by 2
(2+-8)/2 = -6/2 = -3
To find the y coordinate of the midpoint, add the y coordinates of the endpoint and divide by 2
(9+-8)/2 = 1/2
The midpoint is (-3, 1/2)
