Question

The graph shows where four friends' houses are located. How many units is it between Brian's house and Sue's house?

Answer 1

Answer:

Option D. 11 units.

Step-by-step explanation:

Coordinates of Brian's house are (-7, 9)

and coordinates of Sue's house are (-7,-2)

Now we have to find the distance between Brian's and Sue's house.

Since distance between two points = $\sqrt{(x-x')^2+(y-y')^2}$

           = $\sqrt{(-7+7)^2+(9+2)^2}$

           = $\sqrt{(11)^2}$

           = 11 units

Option D is the answer.

Answer 2

-11 i think because it's going down
