Question

medal and fan! newbie to openstudy :)
What is the distance from the coordinate pair
(1, -3) to the coordinate pair (-3, 4)?
Round your answer to the nearest hundredth.

a. 3.31
b. 8.06
c. 7.93
d. 7.81

Answer 1

D or A but im going with A k

Answer 2

are you sure? does anyone else have an opinion?

Answer 3

yes im sure

Answer 4

We can't find distance until we know the slope so y2-y1/x2-x1=m(slope) and then use the equation of a line: y-y1=m(x-x1)

Answer 5

I tried that, it gave me a completely wrong answer @jtryon

Answer 6

@jtryon please please help :(

Answer 7

ok... let me check your work

Answer 8

so what did you get for slope?

Answer 9

I did it on a piece of paper though

Answer 10

slope = ?

Answer 11

I don't know.. Should I go with A?

Answer 12

I want you to understand the process

Answer 13

slope which is m is equal to y2-y1/x2-x1 = -7/4

Answer 14

oh i get it, I tried it again!!! so it is in fact A

Answer 15

there you go :)

Answer 16

thanks!!!
