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

Explanation:

Step 1: Define

Point (-6, -5)

Point (2, 0)

Step 2: Find distance d

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

1. Substitute [DF]:
   `\displaystyle d = √((2+6)^2+(0+5)^2)`
2. Add:
   `\displaystyle d = √((8)^2+(5)^2)`
3. Exponents:
   `\displaystyle d = √(64+25)`
4. Add:
   `\displaystyle d = √(89)`
