Step-by-step 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

Substitute [DF]: $\displaystyle d = \sqrt{(2+6)^2+(0+5)^2}$
Add: $\displaystyle d = \sqrt{(8)^2+(5)^2}$
Exponents: $\displaystyle d = \sqrt{64+25}$
Add: $\displaystyle d = \sqrt{89}$
