Final answer:
The midpoint between points A (7, -9) and D (3, 5) is calculated by averaging the x and y coordinates separately, resulting in the midpoint (5, -2).
Step-by-step explanation:
To find the midpoint between points A (7, -9) and D (3, 5), you need to calculate the average of the x-coordinates and the average of the y-coordinates separately. For the x-coordinates, add 7 and 3 and divide by 2 to get 5. For the y-coordinates, add -9 and 5 and divide by 2 to get -2. Therefore, the midpoint between points A and D is (5, -2).
