ok for this problem you have to have y by itself
OpenStudy (anonymous):
Ok, what is next
OpenStudy (anonymous):
y=mx+b
OpenStudy (anonymous):
slope and b is the y intercept (where the line begins)

m=slope
OpenStudy (anonymous):
Ok, so what is the answer? :) Usually when I have the answer I can see how to do it :)
OpenStudy (anonymous):
im going to explain how to work it out first
OpenStudy (anonymous):
Ok
OpenStudy (anonymous):
its says that the slope of the line is 9/4.......and i told u in the equation y=mx+b m=slope

Ok...
OpenStudy (anonymous):
all you do is replace the m with 9/4
OpenStudy (anonymous):
so y=9/4x + b
OpenStudy (anonymous):
Ok, but there are multiple answers
OpenStudy (anonymous):
So would one of them be C?

OpenStudy (anonymous):
I mean D.
OpenStudy (anonymous):
now its saying that the y intercept is -14 and the y intercept is b in the y=mx+b
OpenStudy (anonymous):
So 1 of the answers would be C.?
OpenStudy (anonymous):
not D because the 14 is negative
OpenStudy (anonymous):
So C.?

correct
OpenStudy (anonymous):
What are the other correct answers?
OpenStudy (anonymous):
ok so we have a and b left they have to be in the form y=mx+b since there are other terms with the y we are going to have to get the y by itself
OpenStudy (anonymous):
Ok, why can't they be in other forms?
OpenStudy (anonymous):
well it makes it easier to solve that way when u get y by its self it will be y=9/4-14

the answers will be exactly the same
OpenStudy (anonymous):
So it is A & B or just 1 of them?
OpenStudy (anonymous):
just one
OpenStudy (anonymous):
Which one?
OpenStudy (anonymous):
do you want me to explain it

OpenStudy (anonymous):
Sure
OpenStudy (anonymous):
a is -9x+4y=-56 so add 9x to both sides
OpenStudy (anonymous):
So is the other answer A.?
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
Ok, they are the only 2?
