• Distance Formula: $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point C (7, -4)

Point D (-8, -5)

Step 2: Find distance d

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