  • Distance Formula:
    d = √((x_2-x_1)^2+(y_2-y_1)^2)

Explanation:

Step 1: Define

Point C (7, -4)

Point D (-8, -5)

Step 2: Find distance d

  1. Substitute [DF]:
    d = √((-8-7)^2+(-5+4)^2)
  2. Subtract/Add:
    d = √((-15)^2+(-1)^2)
  3. Exponents:
    d = √(225+1)
  4. Add:
    d = √(226)
  5. Evaluate:
    d = 15.0333
  6. Round:
    d = 15.0
