Answer 1

`(4, -3 )`

General Formulas and Concepts:

Pre-Algebra I

• Order of Operations: BPEMDAS

Algebra I

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

Explanation:

Step 1: Define

R (9, 3)

S (-1, -9)

Step 2: Find midpoint

1. Substitute:
   `((9-1)/(2), (3-9)/(2) )`
2. Subtract:
   `((8)/(2), (-6)/(2) )`
3. Divide:
   `(4, -3 )`
