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

Step-by-step explanation:

Step 1: Define

Point (4, 6)

Point (-2, -2)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

  1. Substitute [DF]:                     [tex]\displaystyle d = \sqrt{(-2-4)^2+(-2-6)^2}[/tex]
  2. Subtract:                                [tex]\displaystyle d = \sqrt{(-6)^2+(-8)^2}[/tex]
  3. Exponents:                            [tex]\displaystyle d = \sqrt{36+64}[/tex]
  4. Add:                                       [tex]\displaystyle d = \sqrt{100}[/tex]
  5. Evaluate:                               [tex]\displaystyle d = 10[/tex]
the distance will be 10!
