Question

Use the following four coordinates to determine which one has a distance of 5 units from point A (2, 6).

(7, 5)
(6, 7)
(2, 5)
(5, 2)

Answer 1

@LanguageEnthusiast I chose answer (6,7)

Answer 2

\[d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\]

Do you know how to use that formula?

Answer 3

I believe so.
Let me give it a try

Answer 4

2,6) (6,7)

D= 2-6)2 + (6-7)2
D= (4)2 + (1)2
D= 16 + 1
D= 17?
o-o

Answer 5

Yup, now just keep doing that until you find which one gives you:
\[d=5\]

Answer 6

I think it's (7,5).... I made a grid... and this one was 5 units apart.

Answer 7

(2,6) (7,5)
D=(2-7)2 + (6-5)2
D=(-5)2 + (1)2
D=25 + 1
D= 26

Answer 8

Not right ._.

Answer 9

ERMAHGERD

Answer 10

Try: \[(5,2)\]

Answer 11

Alright.

Answer 12

(2,6) (5,2)
D= (2-5)2 + (6-2)2
D= (3)2 + (4)2
D= 9 + 16

Answer 13

? ;-;

Answer 14

\[9 + 16 = 25\]
\[\sqrt{25}=5\]

Answer 15

:D Thank you. I always forget that last step.

Answer 16

No problem, it happens to all of us. :-P

Answer 17

Help me out with a few more? This will help me get my grade up quite a lot. Math really stresses me out... I over think it.
