Point a is located at (_2, _6), and d is located at (_6, 8). find the coordinates of the point that lies halfway between a and d.
(0, 2)

(_2, 3)

(_3, 0)

(_4, 1)

This (as well as many other) question is misclassified, This belongs to mathematics.

A: ( - 2, - 6) ;  D ( - 6, 8)

x-coordinate of the middle point: [-2 + (- 6)] / 2 = - 4
y-coordinate of the middle point: [-6 + 8] / 2 = 1

( - 4, 1)
