Distance Formula:

Step-by-step explanation:

Step 1: Define

Identify points from graph

Point X(-8, 1)

Point Y(2, 5)

Step 2: Find distance d

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

Substitute in points [Distance Formula]:                                                         [√Radical] (Parenthesis) Subtract:                                                                   [√Radical] Evaluate exponents:                                                                       [√Radical] Add:                                                                                                 [√Radical] Evaluate:                                                                                         Round:
