What are you solving for...

@kdblankenship48
OpenStudy (anonymous):
Putting it in standard form ax+by=c
TheSmartOne (thesmartone):
So first we need to take care of y-(-2)
then we need to distribute the -3/4 into the parenthesis.

\[a-(-b)=a+b\]
so what does y-(-2)=??
OpenStudy (anonymous):
lol can you explain it a little simpler, im a junior in highschool.
TheSmartOne (thesmartone):
well so am I...
OpenStudy (anonymous):
well, im struggling and you seem a lot smarter.
TheSmartOne (thesmartone):
When you subtract a negative number you have to add them together...

i got that part
TheSmartOne (thesmartone):
so a-(-b)=a+b
and y-(-2)=???
a=y
b=2
Then y+2
So y-(-2)=y+2
OpenStudy (anonymous):
lol i was gonna put that but i thought i was wrong
TheSmartOne (thesmartone):
Always believe in yourself. If you get it wrong.. I am here to help you understand...
OpenStudy (anonymous):
so y+2=-3/4x-6/8?

TheSmartOne (thesmartone):
umm.. no
OpenStudy (anonymous):
ughhhh
TheSmartOne (thesmartone):
Ok so we got the y+2 lets leave that alone. Lets distribute the -3/4 inside...
OpenStudy (anonymous):
okay
TheSmartOne (thesmartone):
\[\frac{ -3 }{ 4 }(x-2)=\frac{ -3 }{ 4 }x -(2)(\frac{ -3 }{4 })\]

Distributing inside means multiplying it inside to each value...
TheSmartOne (thesmartone):
\[a(x+y)=ax+ay\]
OpenStudy (anonymous):
i need to get the equation to y=mx+b and then change it to standard form
TheSmartOne (thesmartone):
So you should get so far
\[y+2=\frac{ -3 }{ 4 }x+\frac{ 3 }{ 2 }\]
OpenStudy (anonymous):
yaaaaassss
thats what i got

Because \[\frac{ 3 }{ 4 }\times 2=\frac{ 3 }{ 2 }\times 1\]
TheSmartOne (thesmartone):
\[y+2-2=\frac{ -3 }{ 4 }x+\frac{ 3 }{ 2 }-2\]
TheSmartOne (thesmartone):
So what does y=??
OpenStudy (anonymous):
okay y=-3/4x-1/2?
TheSmartOne (thesmartone):
\[y=-\frac{ 3 }{ 4 }x-\frac{ 1 }{2 }\] is correct. ^_^

OpenStudy (anonymous):
yay! okay, now what?
TheSmartOne (thesmartone):
we just add 3/4x to get it into Ax+By=C
OpenStudy (anonymous):
so 3/4x+2y?
TheSmartOne (thesmartone):
No it would just be
3/4x+y=-1/2
OpenStudy (anonymous):
oh okay

TheSmartOne (thesmartone):
There is an implied 1 in front of the y because 1y=y, 1x=x, 1a=a
OpenStudy (anonymous):
gotcha
OpenStudy (anonymous):
so that's the answer?
TheSmartOne (thesmartone):
Yup...
TheSmartOne (thesmartone):
You are new here right..

TheSmartOne (thesmartone):
Wait we can have his talk in the messages...
