<u>Algebra II</u>

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

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

Point (1, 5)

Point (-8, 4)

<u>Step 2: Find distance </u><em><u>d</u></em>

Simply plug in the 2 coordinates into the distance formula to find distance <em>d</em>

  1. Substitute in points [Distance Formula]:                                                         \displaystyle d = \sqrt{(-8-1)^2+(4-5)^2}
  2. [√Radical] (Parenthesis) Subtract:                                                                   \displaystyle d = \sqrt{(-9)^2+(-1)^2}
  3. [√Radical] Evaluate exponents:                                                                       \displaystyle d = \sqrt{81+1}
  4. [√Radical] Add:                                                                                                 \displaystyle d = \sqrt{82}
