Question

how do i find the distance between these pairs of points: (-2,-2).. (-4,-1)?

Answer 1

please walk me through it

Answer 2

\[\sqrt{(x-x2)(y-y2)}\]

Answer 3

in english,
the distance between -2 and-4 on the x axis is 2
the distance between -2 and-1 on the y axis is 1
pythatoras tells you that
\[d^2=2^2+1^2=4+1=5\] so
\[d=\sqrt{5}\]

Answer 4

d=sqrt[(x2-x1)^2+(y2-y1)^2]

Answer 5

@math pro and zbay u forgot exponents

Answer 6

you can use the formula
\[d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\]
but just make sure you
1) subtract
2) square
3) add
4) take the square root

Answer 7

yes

Answer 8

lol sorry dont mean to be mean

Answer 9

@satellite in that order? and everyone thanks for the help :)

Answer 10

if u just plug the whole thing in caclulator it will work just fine too :P

Answer 11

if you want to use the formula here you can write
\[\sqrt{(-2-(-4))^2+(-2-(-1))^2}\]
\[\sqrt{2^2+1^2}\]
\[\sqrt{4+1}\]
\[\sqrt{5}\]

Answer 12

thanks everyone!!!!!

Answer 13

first subtract in each coordinate. be careful of the signs, and make sure you are subtracting x's from x's and y's from y's

Answer 14

then square each one
then add
then take the square root.
don't try any shortcuts!

Answer 15

thanks
