Okay so you're looking for the change from one point to the other?

OpenStudy (anonymous):

Yeah

OpenStudy (ashes.boom):

Do you know which of the two numbers in the first point is the y axis and which is the x axis?

OpenStudy (anonymous):

Yes

OpenStudy (ashes.boom):

Okay starting with the first number you want to get from 4 to -4, how do you do that?

OpenStudy (anonymous):

Do you subtract?

OpenStudy (ashes.boom):

yes you want to subtract 8

OpenStudy (ashes.boom):

the first number represents the x axis so do you move up and down or left and right?

OpenStudy (anonymous):

left and right

OpenStudy (anonymous):

so it would be right for 8

OpenStudy (ashes.boom):

Right would be adding and you want to subtract

OpenStudy (ashes.boom):

so you would move 8 to the left... does that make sense?

OpenStudy (anonymous):

Yeah

OpenStudy (anonymous):

what about the other numbers

OpenStudy (ashes.boom):

okay now for the second number you have to get from -4 to 7 but its on the y axis so you move up and down

OpenStudy (anonymous):

Okay

OpenStudy (ashes.boom):

so do you add or subtract to get from -4 to 7?

OpenStudy (anonymous):

add?

OpenStudy (ashes.boom):

yep

OpenStudy (anonymous):

I got 3

OpenStudy (ashes.boom):

you mean add three?

OpenStudy (anonymous):

yeah

OpenStudy (ashes.boom):

if you add three to -4 you get -1 so you have to add more to get to 7

OpenStudy (anonymous):

Okay so I would add 11

OpenStudy (ashes.boom):

if you add 4 you would get to 0 and then you add 7 so yes 4 + 7 = 11 :)

OpenStudy (ashes.boom):

so its adding 11 so you move up 11 on the y axis

OpenStudy (anonymous):

OKay so the answer would be D

OpenStudy (ashes.boom):

Yep! :) I have to go to class now so i hope that helped

OpenStudy (anonymous):

Thanks!

OpenStudy (ashes.boom):

Your welcome :D Good luck with the rest!!
