if you graph this will it be a solution or not a solution?
OpenStudy (anonymous):
-1/3x + y = –1
solve for y
OpenStudy (anonymous):
can i move the numbers around?
OpenStudy (anonymous):
put it in this form
y = mx + b
OpenStudy (anonymous):
like-
-1/3x+-1=y

yea
OpenStudy (anonymous):
wrong
OpenStudy (anonymous):
why?
OpenStudy (anonymous):
didn't you move y to the other side? what should the sign be?
OpenStudy (anonymous):
y=-1+ -1/3x ?

im lost?
OpenStudy (anonymous):
-1/3x + y = –1
+1/3x +1/3x
y = 1/3x - 1
OpenStudy (anonymous):
oh okay
OpenStudy (anonymous):
y = 1/3x - 1
y = 1/3x + 4
now graph them
OpenStudy (anonymous):
thanks,

did you graph them?
OpenStudy (anonymous):
i am in a second
OpenStudy (anonymous):
so its a solution?
OpenStudy (anonymous):
do the lines cross somewhere?
OpenStudy (anonymous):
on the a.b.c.d. all of the lines are paralell and they are asking if solution or not.

lines are parallel so they will never cross, so no solution
OpenStudy (anonymous):
dont forget my $10 :p
OpenStudy (anonymous):
idk its like two paraell lines going up and its says is solution-A
then same graph but its say no solution-b
OpenStudy (anonymous):
|dw:1350402108007:dw|
no solution
OpenStudy (anonymous):
A and B

OpenStudy (anonymous):
thats the right graph
OpenStudy (anonymous):
c and d
OpenStudy (anonymous):
so it b not a solution
OpenStudy (anonymous):
correct
OpenStudy (anonymous):
okay thanks!
