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

Step-by-step explanation:

Step 1: Define

Point C (7, -4)

Point D (-8, -5)

Step 2: Find distance d

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