Question

What is the distance between points (4, −7) and (−5, 9)? Round to the nearest tenth of a unit.

Answer 1

ok subtract x from x and y from y

Answer 2

4 - -5 and -7 - 9

Answer 3

nm

Answer 4

do you know the distance formula between 2 given points?

Answer 5

d= \[\sqrt{(x^2-x^1)^2}+(y^2-y^1)^2\]

Answer 6

if the 2 points are (x1,y1) and (x2,y2)

distance = sqrt((y2-y1)^2 + (x2-x1)^2))

Answer 7

-5 - 4 and ^2 them =)

Answer 8

then get the sqrt of that answer =)

Answer 9

3 ...

Answer 10

plug in x1 = 4, x2 = -5 , y1 = -7 and y2 = 9 into the formula and work it out

Answer 11

now do 3+(9- -7)^2

Answer 12

9- -7 = 16

Answer 13

16^2 = ?

Answer 14

now you finish it up

Answer 15

256

Answer 16

????

Answer 17

i screwed up lol

Answer 18

oh well d =18.4

Answer 19

d = distance

Answer 20

thats the anwser

Answer 21

...

Answer 22

yes =)
