Either is correct. Each is convenient for different purposes.I gave seen standard form defined as ax+by=c OR ax+by+c=0
which is correct?
Ironically, there is no standard definition for the "standard form" for the equation of a straight line. The "correct" form is whatever your particular textbook or particular instructor wants, at a particular time, in a particular course. Next semester, the definition may change.I gave seen standard form defined as ax+by=c. And ax+by+c=0
which is correct?
