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

Step-by-step explanation:

Step 1: Define

Point (5, 1)

Point (-3, -5)

Step 2: Find distance d

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

1. Substitute in points [Distance Formula]:                                                         $\displaystyle d = \sqrt{(-3-5)^2+(-5-1)^2}$
2. [√Radical] (Parenthesis) Subtract:                                                                   $\displaystyle d = \sqrt{(-8)^2+(-6)^2}$
3. [√Radical] Evaluate exponents:                                                                       $\displaystyle d = \sqrt{64+36}$
4. [√Radical] Add:                                                                                                 $\displaystyle d = \sqrt{100}$
5. [√Radical] Evaluate:                                                                                         $d = 10$
