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

Algebra II

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

Step-by-step 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]:                    $\displaystyle d = \sqrt{(6+3)^2+(-9+4)^2}$
2. (Parenthesis) Add:                              $\displaystyle d = \sqrt{(9)^2+(-5)^2}$
3. [√Radical] Exponents:                        $\displaystyle d = \sqrt{81+25}$
4. [√Radical] Add:                                   $\displaystyle d = \sqrt{106}$
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.

Answer 2

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!
