Algebra II

• Distance Formula:
  `\displaystyle d = √((x_2-x_1)^2+(y_2-y_1)^2)`

Explanation:

Step 1: Define

Point (1, 10)

Point (5, 15)

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 = √((5-1)^2+(15-10)^2)`
2. [√Radical] (Parenthesis) Subtract:
   `\displaystyle d = √((4)^2+(5)^2)`
3. [√Radical] Evaluate exponents:
   `\displaystyle d = √(16+25)`
4. [√Radical] Add:
   `\displaystyle d = √(41)`
