Question

what is the distance formula?

Answer 1

\[\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}\]

Answer 2

squareroot of (x2-x1)^2 + (y2-y1)^2

Answer 3

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

Answer 4

\[\sqrt{(x1-y1)^{2}+(x2-y2)^{2}}\]

Answer 5

drawing a picture so you can see whats going on, one sec

Answer 6

the question is this (-1,8), (-8,3)

Answer 7

squareroot of (-8-1)^2 + (3-8)^2

Answer 8

the square root of (x1-x2)squared minus (y1-y2)squared

Answer 9

from here to there ....

Answer 10

lovely joe

Answer 11

every time i post a picture and look at it i think, "....is my handwriting really that bad? O.o"

Answer 12

\[\sqrt{(-8-(-1))^2+(3-8)^2}=\sqrt{(-7)^2+(-5)^2}=\sqrt{49+25}=\sqrt{74}\]

Answer 13

it is bad but readable lol

Answer 14

\[\sqrt{(3-8)^{2}+(-8+1)^{2}} =\sqrt{(11)^{2}+(-7)^{2}} =\sqrt{121+49}=\sqrt{170}\]

Answer 15

you should my writing it is horrible

Answer 16

worse than yours probably

Answer 17

3-8=-5

Answer 18

i thouht -8-(-1) go first

Answer 19

addition is commutative a+b=b+a
