@16dsanders

OpenStudy (anonymous):

you can use two point form for this question btw no option matches the answer

OpenStudy (anonymous):

C?

OpenStudy (anonymous):

do you have any idea of the slope of a line?

OpenStudy (anonymous):

i think c

OpenStudy (anonymous):

Its a No Slope -_-

OpenStudy (anonymous):

So it would be b?

OpenStudy (anonymous):

i am writing the standard form of a line passing from two points (x1,y1) , (x2,y2) y-y1 = (y2-y1)/(x2-x1) [x-x1] now you have to substitute the two points

OpenStudy (anonymous):

ITS A ZERO SLOPE I TOLD YOU THIS -_-

OpenStudy (dayakar):

ur options are wrong

OpenStudy (dayakar):

equqtion of the line passing through (x1,y1) =(-3,1) and (x2,y2) = (3,4) is

OpenStudy (anonymous):

soo All of my answers are Wrong? XD

OpenStudy (dayakar):

(y-y1) (x2-x1) = (y2-y1)(x-x1)

OpenStudy (dayakar):

yes ,i am finding the equation just wait

OpenStudy (dayakar):

(y-1)[3-(-3)] =(4-1)[x-(-3)]

OpenStudy (dayakar):

(y-1)(3+3) =3(x+3)

OpenStudy (dayakar):

(y-1)6/3 = x+3

OpenStudy (dayakar):

r u following

OpenStudy (dayakar):

(y-1)2=x+3

OpenStudy (dayakar):

2y-2 =x+3

OpenStudy (dayakar):

-2-3 =x-2y

OpenStudy (dayakar):

-5= x-2y

OpenStudy (dayakar):

required line equation is x-2y = -5

OpenStudy (dayakar):

r u clear

OpenStudy (anonymous):

@dayakar Yes

OpenStudy (dayakar):

ok, buy :)
