If the linear equation 3x = 9 − 2y is written in standard form, what is the value of B?

Question

ghazi · Answer

where is B??

anonymous · Answer

i dont know

anonymous · Answer

you have to put the equation in standard form but i don't know how to

chihiroasleaf · Answer

3x+2y=9 is the standard form

anonymous · Answer

Standard form is Ax+By=C without fractions and where A is non-negative

anonymous · Answer

okay...

ghazi · Answer

$$3x+2y=9......\frac{ 3x }{ 9 }+\frac{ 2y }{ 9 }=1$$ now yur B= 9/2

anonymous · Answer

so the answer is 9/2????

anonymous · Answer

@chihiroasleaf nailed it... What is B in his statement?

chihiroasleaf · Answer

@ghazi  should we make the constant become 1 to be the standard form?

anonymous · Answer

no fractions allowed

chihiroasleaf · Answer

@EulerGroupie I don't know what is the B, it's not clear on the question
if B is the constant of 'y' then B = 2

ghazi · Answer

yes....your standard equation is like$$\frac{ x }{ A }+\frac{ y }{ B }=1$$

anonymous · Answer

Sorry, but no.  It is Ax+By=C

anonymous · Answer

so what would the answer be then?

anonymous · Answer

2

ghazi · Answer

sorry it's 9/2

chihiroasleaf · Answer

I think @EulerGroupie is correct you can read this http://www.algebralab.org/studyaids/studyaid.aspx?file=algebra1_5-5.xml so the answer is 2

anonymous · Answer

I deal with this all the time... don't trust me... try a web search.

anonymous · Answer

are you being serious or sarcastic?^

anonymous · Answer

Standard equation for a plane
Ax+By+Cz=D

anonymous · Answer

No, serious.  You don't have to trust me.  I did a web search, it came up immediately.

anonymous · Answer

so the answer is 2?

chihiroasleaf · Answer

yes... :)

ghazi · Answer

yes ...it was my fallacy @EulerGroupie   is right

anonymous · Answer

No problems @ghazi.  I know that you have amazing skills.  I tutor at a community college and there are some questions that I field about 10 times per semster and this is one of them.  I personally think the form is almost useless.  It works well to find x and y intercepts, otherwise I like slope intercept or point slope better.

ghazi · Answer

exactly ....actually what i wrote is for finding slope....

anonymous · Answer

okay thanks guys! i appreciate it (:

anonymous · Answer

You're welcome.

ghazi · Answer

not slope it's intercept

chihiroasleaf · Answer

you're welcome :)

anonymous · Answer

Cool, an analytic form (like conic sections) of a line that states the intercepts.  I like it @ghazi.  That is one of the reasons that I like this site... new perspectives.
