Algebra II

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

Step-by-step explanation:

Step 1: Define

Identify

Point (-1, -8)

Point (-4, -4)

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]:                                                         $\displaystyle d = \sqrt{(-4--1)^2+(-4--8)^2}$
2. [√Radical] (Parenthesis) Subtract:                                                                   $\displaystyle d = \sqrt{(-3)^2+(4)^2}$
3. [√Radical] Evaluate exponents:                                                                       $\displaystyle d = \sqrt{9+16}$
4. [√Radical] Add:                                                                                                 $\displaystyle d = \sqrt{25}$
5. [√Radical] Evaluate:                                                                                           $\displaystyle d = 5$
