Question

I asked a ? earlier and I still do not understand it could someone please help...Find the distance between these 2 points (-3,5) & (6,-2). Be sure that the answer is simplified and in radical form. Show all work.

Answer 1

Plot the points and use pythagorean theorem or distance formula

Answer 2

thats what the last person told me and apparently i am not doing something right

Answer 3

You have graph paper right?

Answer 4

no i am doing it all on computer

Answer 5

Do you have a graphic plotting device on your computer?

Answer 6

no we are not allowed to do it that way. I meant my assignment is on computer. I am having to do it all on paper and show all of my work

Answer 7

you shouldn't do math without graph paper handy. Math 101

Answer 8

ok I will remember that....i have the distance formula as sqrt((x2-x1)^2+(y2-y1)^2) but I do not know how to put everything into that formula or where to go from there

Answer 9

Label the points and plug them in. It's easy

Answer 10

ok let me see here give me a sec.

Answer 11

when it comes to x1 and x2 does it matter which x # I put where

Answer 12

yes it does

Answer 13

label your points like this:

(x1,y1) (x2, y2)

Answer 14

ok so I would insert -3 in the x2 spot right

Answer 15

ok now im confused

Answer 16

okay, let me show you

Answer 17

(x1,y1) = (-3,5)
(x2,y2) = (6,-2)

Is that clear enough?

Answer 18

so when it says x2 or y2 that just means its place and not to the 2nd power

Answer 19

yes, correct

Answer 20

ok give me a sec

Answer 21

Ok when I plug them all in I got sqrt((6-(-3))^2+(-2-(-5)^2=(3)^2+(3)^2=9+9=81

Answer 22

You did something wrong. For that first one (6-(-3)^2 = (6+3)^2 = 9^2, not 3^2

Answer 23

This is why graphing method is better

Answer 24

But also 9+9 = 18 , not 81. You're supposed to add at the end not multiply

Answer 25

Ok so the 2nd 1 would be (-2-(-5)^2=(7)^2=14

Answer 26

You had the second one right already ....face palm :P

Answer 27

(-2-(-5))^2 = (-2+5)^2 = (3)^2 = 9

Answer 28

so my points would be (18,9)

Answer 29

You're not trying to find anymore points. You're trying to find DISTANCE

Answer 30

ok so what do i have to do from here

Answer 31

Basically, when you calculated it the first time, you made a couple of adding mistakes. That's all. Try it again.

Answer 32

And post your steps just like last time. Just be more careful

Answer 33

what do you mean

Answer 34

i meant for you to try to calculate it again. But try to add correctly this time.

Answer 35

it would b 6 and not 9

Answer 36

the answer is d = 3root(10). Try to figure out how I got that

Answer 37

that would be 130
