Take the first equation and arrange it in standard form then tell me the answer..
OpenStudy (anonymous):
3x – y = –3
standard form : ax + by = c
isnt it in standard form?
OpenStudy (anonymous):
can you turn it into y=mx+c form?
OpenStudy (anonymous):
yes. -y = 3x + 3

wrong.one little mistake..
OpenStudy (anonymous):
whats that?
OpenStudy (anonymous):
it will be y=3x+3
OpenStudy (anonymous):
do you get it?
OpenStudy (anonymous):
yes, took me a while but i understand. By changing the firstt equation into standard form, do that make it the answer? or should i change them all?

Let first draw the conclusion for the first one.what is the y-intercept of the first equation?
OpenStudy (anonymous):
-4
OpenStudy (anonymous):
no
1
OpenStudy (anonymous):
No. c in the equation is the y-intercept.In y=3x+3,it will be +3.
OpenStudy (anonymous):
oh, ok

is that true for graph?
OpenStudy (anonymous):
no
OpenStudy (anonymous):
good.so first is wrong.Lets proceed to the second one.What do yo think about it?
OpenStudy (anonymous):
the y intercept is negative 3 and that is true for the graph
OpenStudy (anonymous):
good.so that will be the answer

wait... 3x – y = 3 ?
OpenStudy (anonymous):
yes.
OpenStudy (anonymous):
But there is a problem in options.option 2 and 3 are same.
OpenStudy (anonymous):
what does that mean?
OpenStudy (anonymous):
it means that you can write y=3x-3(answer) in both ways.
