What are the coordinates of the midpoint of line segment E F if point E is located at negative 12 comma 5 and point F is located at 7 comma negative 9 ?

Use the midpoint formula: average the x-coordinates and average the y-coordinates. The x-coordinate is (−12 + 7) ÷ 2 = −5/2, and the y-coordinate is (5 + (−9)) ÷ 2 = −2. The midpoint is (−5/2, −2), which is choice D.
