  • Reading a coordinate plane
  • Coordinates (x, y)

Algebra II

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

Step-by-step explanation:

Step 1: Define

Identify points from graph.

Point (8, 5)

Point (4, 2)

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