• Coordinates (x, y)

Algebra II

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

Step-by-step explanation:

Step 1: Define

Point P1(0, 0)

Point P2(5, 6)

Step 2: Identify

x₁ = 0, y₁ = 0

x₂ = 5, y₂ = 6

Step 3: Find distance d

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

1. Substitute in points [Distance Formula]:                                                         $\displaystyle d = \sqrt{(5-0)^2+(6-0)^2}$
2. [Distance] [√Radical] (Parenthesis) Subtract:                                                 $\displaystyle d = \sqrt{(5)^2+(6)^2}$
3. [Distance] [√Radical] Evaluate exponents:                                                     $\displaystyle d = \sqrt{25+36}$
4. [Distance] [√Radical] Add:                                                                               $\displaystyle d = \sqrt{61}$
