What is y + 11 = 1/3 (x + 3) in standard form?

Standard form is y=Mx+b so first step is to isolate y:

Y=1/3 (x+3) - 11

Then use order of operations to simplify the x to a whole number. First multiply by three:

3y=x+3-33

Now combine like terms:

3y=x-30

Finally,

Divide to make y have a coefficient if one:

Y = 1/3x - 10
