Answer:

Coordinate grids are pretty fun and easy, your answer is gonna be 22 units im pretty sure! Have not done them in a while, so I hope this is correct!

Answer:

10.6 units

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

Algebra I

  • Reading a Cartesian Plane
  • Coordinates (x, y)

Algebra II

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

Explanation:

Step 1: Define

Find points from graph.

Point B(-3, -4)

Point D(6, -9)

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 = √((6+3)^2+(-9+4)^2)
  2. (Parenthesis) Add:
    \displaystyle d = √((9)^2+(-5)^2)
  3. [√Radical] Exponents:
    \displaystyle d = √(81+25)
  4. [√Radical] Add:
    \displaystyle d = √(106)
  5. [√Radical] Evaluate:
    \displaystyle d = 10.2956
  6. Round:
    \displaystyle d \approx 10.3

All the answer choices are wrong. Closest answer is 10.6 units.
