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

Explanation:

Step 1: Define

Point J (15, -13)

Point K (-9, 27)

Step 2: Find Midpoint

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

1. Substitute [MP]:
   `((15-9)/(2),(-13+27)/(2))`
2. Subtract/Add:
   `((6)/(2),(14)/(2))`
3. Divide:
   `(3,7)`
