Please help me! How do I convert this to standard form?

OpenStudy (steve816):

\[y=\frac{ -11 }{ 9 x}+\frac{ 1 }{ 3 }\]

OpenStudy (anonymous):

is y the LHS of an equation for a line? If so, the x should be moved to the numerator.

OpenStudy (steve816):

Sorry, I kind of messed up on writing the equation. It's supposed to be like this:\[y=-\frac{ 11 }{ 9 }x+\frac{ 1 }{ 3 }\]

OpenStudy (steve816):

Umm can you please give me a demonstration using this example??

OpenStudy (anonymous):

Ax+By=C Eliminate the fractions in the problem. Do you know how you can do that?

OpenStudy (anonymous):

Denominators are 9 & 3 which equal 27. If you multiply the entire equation by the common denominator (27), you can eliminate the fraction. 27 (y=-11x/9 + 1/3) 27y = -33x+9

OpenStudy (anonymous):

To reach standard form, get the x & y on the same side of the equation.

OpenStudy (anonymous):

Get ride of the fractions by multiplying each side of the equation by 27. 27 y = -33 x + 9 Then move the x term to the LHS. 33x +27y = 9

OpenStudy (steve816):

Wait, can't you multiply the equations by 9?

OpenStudy (anonymous):

Yes.

OpenStudy (anonymous):

the word ride should have been spelled rid.

OpenStudy (anonymous):

You could. 9y = -11x+3 That should have been the choice...wasn't thinking...rusty

OpenStudy (anonymous):

Would give you 11x + 9y = 3

OpenStudy (anonymous):

Divide each side of the following equation by 3. 33x +27y = 9

OpenStudy (steve816):

Okay I understand this problem now. Thanks so much @robtobey and @DSS Wish I could give more then 1 medal but really appreciate you guys' help :)
