What is the distance between points E and F?


A) 2 (sqroot) 5
B) 4 (sqroot) 3
C) (sqroot) 3
D) (sqroot) 5

Answer 1

what are the coordinates of point E and F??

Answer 2

does that help?

Answer 3

i already saw that......I want you to tell me what they are....

Answer 4

oh (-3,2) and (-2,4)

Answer 5

okay, so the distance formula says that if you have two points
\[(x_1, y_1) and (x_2,y_2)\]
and you are finding the distance between these two poinbts,
\[D = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}\]

Answer 6

**points

Answer 7

does that help??

Answer 8

yes

Answer 9

so what do you get for the answer??

Answer 10

i got 8

Answer 11

are you sure??
i got a different answer....

Answer 12

wait I messed up...

Answer 13

\[D = \sqrt{(-2-(-3))^2 + (4-2)^2}\]

Answer 14

i got d

Answer 15

what is d??

Answer 16

\[\sqrt{5}\]

Answer 17

okay......that is correct!

Answer 18

thank you so much!!!

Answer 19

you are welcome!...(:
