Convert from slope-intercept form (y = mx+b) to standard form (Ax+By = C)
 
 
   Start with the given equation
 
 
   Subtract 3x from both sides
 
 
   Simplify
 
 
   Multiply both sides by -1 to make the A coefficient positive (note: this step may be optional; it will depend on your teacher and/or textbook)
 
 
   Distribute and simplify
 
  The original equation   (slope-intercept form) is equivalent to   (standard form where A > 0)
 
  The equation   is in the form   where  ,   and
