I really need assistance. Can anybody help me?

OpenStudy (dawnr):

that depends ..what do you need? XD

OpenStudy (anonymous):

Point A is located at (0, 4) and point B is located at (−2, −3). Find the x value for the point that is 1 over 4 the distance from point A to point B.

OpenStudy (dawnr):

just draw it!

OpenStudy (anonymous):

−1.5 −2 −0.5 −1

OpenStudy (anonymous):

but what does it mean by 1/4 the distance?

OpenStudy (dawnr):

1 over 4 is 5 XD

OpenStudy (anonymous):

what formula do i use?

OpenStudy (dawnr):

try to draw both and the x as a point (such as A or B)

OpenStudy (dawnr):

as for the formula you have this one: A(x1,y1) ; B(x2,y2), d(A,B)=AB=sqrt(x2-x1)^2 +(y2-y1)^2 in your case x is d

OpenStudy (anonymous):

i don't get it but thanks anyway

OpenStudy (dawnr):

XD for A(x1=0,y1= 4) for B (x2=−2, y2=−3)

OpenStudy (anonymous):

so -3-4/-2-0

OpenStudy (anonymous):

-7/-2

OpenStudy (anonymous):

i got 3.5

OpenStudy (dawnr):

how did you get that? o.O

OpenStudy (anonymous):

i used the formula slope, m= y2-y1/x2-x1

OpenStudy (dawnr):

\[\sqrt{(-2-0)^{2}+(-3-4)^{2}}=\sqrt{(-2)^{2}+(-7)^{2}}=\sqrt{4 + 49}=\sqrt{53}\]

OpenStudy (dawnr):

do you have a solution to it..the exact number?

OpenStudy (anonymous):

do you mean the choices for the answer because this question is multiple choice

OpenStudy (dawnr):

are those the one you posted above?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

but i can repost them

OpenStudy (anonymous):

a)−1.5 b) −2 c)−0.5 d)−1

OpenStudy (anonymous):

|dw:1402939150351:dw|

OpenStudy (anonymous):

correction -0.5

OpenStudy (anonymous):

O, wow, well thanks for the help; i needed it

OpenStudy (anonymous):
