• Coordinates (x, y)
• Midpoint Formula:
  `\displaystyle ((x_1 + x_1)/(2), (y_1 + y_2)/(2))`

Explanation:

Step 1: Define

Point A(-2, 5)

Point B(-4, 7)

Step 2: Find Midpoint

1. Substitute in points [Midpoint Formula]:
   `\displaystyle ((-2 + -4)/(2), (5 + 7)/(2))`
2. Add:
   `\displaystyle ((-6)/(2), (12)/(2))`
3. Divide:
   `\displaystyle (-3, 6)`
