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

Step-by-step explanation:

Step 1: Define

Point A (-3, 1)

Point B (-1, -1)

Step 2: Find distance d

  1. Substitute:                    [tex]d = \sqrt{(-1+3)^2+(-1-1)^2}[/tex]
  2. Add/Subtract:               [tex]d = \sqrt{(2)^2+(-2)^2}[/tex]
  3. Exponents:                   [tex]d = \sqrt{4+4}[/tex]
  4. Add:                              [tex]d = \sqrt{8}[/tex]
  5. Simplify:                        [tex]d = 2\sqrt{2}[/tex]
  6. Evaluate:                       [tex]d = 2.82843[/tex]
  7. Round:                          [tex]d \approx 2.8[/tex]

Answer:  d = 2.83

Step-by-step explanation: The distance between AB rounded to the nearest tenth is 2.83
