• Midpoint Formula:
  `((x_1+x_2)/(2),(y_1+y_2)/(2))`

Explanation:

Step 1: Define

Point A (1, -2)

Point B (1, -1)

Step 2: Find Midpoint

Simply plug in your coordinates into the midpoint formula to find midpoint

1. Substitute [MF]:
   `((1+1)/(2),(-2-1)/(2))`
2. Add/Subtract:
   `((2)/(2),(-3)/(2))`
3. Divide:
   `(1,-1.5)`
