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

Step-by-step explanation:

Step 1: Define

Point (-5, -2) → x₁ = -5, y₁ = -2

Point (-3, 4) → x₂ = -3, y₂ = 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]:                                                       $\displaystyle d = \sqrt{(-3+5)^2+(4+2)^2}$
2. [√Radical] (Parenthesis) Add:                                                                        $\displaystyle d = \sqrt{(2)^2+(6)^2}$
3. [√Radical] Evaluate exponents:                                                                    $\displaystyle d = \sqrt{4+36}$
4. [√Radical] Add:                                                                                               $\displaystyle d = \sqrt{40}$
5. [√Radical] Simplify:                                                                                         $\displaystyle d = 2\sqrt{10}$
