I'm confused, the majority of the things that I've seen have said Ax + By = C, in which case I just need to move my 36 to the other side. However, I'm not sure what you're claiming standard form to be, because just moving x to the other side is not standard form either.  You need integers, and I believe that the coefficient of x is typically said to be a positive integer.

Slope/y-intercept form Or you just do Ax+by=C get constant on one side, and variables on other.

So if it's y = 5/9x + b it's already standard form... No. That's slope-intercept form. NZ Guy Posted at 4:19 pm on July 6, 2009 What is standard form? I spent 5 years at high school (until the end) and i have only ever heard of Standard form on here, we must call it something else over here.

Edit:  What kind of problems are you doing? LiveForeverDieTonite Posted at 4:18 pm on July 6, 2009 Ax + By + C = 0 -5x + 9y - 45 = 0 or Ax + By = C -5x + 9y = 45 Shush Posted at 4:16 pm on July 6, 2009 Just move the x to the left side.
