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

Explanation:

Step 1: Define

Find points from graph.

Point A(-2, 5)

Point B(5, 5)

Step 2: Find distance d

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

  1. Substitute in points [DF]:
    \displaystyle d = √((5--2)^2+(5-5)^2)
  2. (Parenthesis) Simplify:
    \displaystyle d = √((5+2)^2+(5-5)^2)
  3. (Parenthesis) Add/Subtract:
    \displaystyle d = √((7)^2+(0)^2)
  4. [√Radical] Exponent:
    \displaystyle d = √((7)^2)
  5. [√Radical] Evaluate:
    \displaystyle d = 7
