General Form of a Equation (2 Viewers)

[maths94]

when writing the general form of a equation should the x always b a positive or it doesnt matter? example. btw they are 2 totally different equations

4x+y-10=0...[1]

-4x+2y-20=0...[2]

are they both correct? or which one is correct?

 

[occer]

They are both correct if I can remember. I prefer the first term to be a positive though.

only the first one is correct. general form is ax+by+c where a is always a positive integer

oh k thank you

General form of line:

- x must be positive
- no fractions

wiki says convention, not rule, is a is positive, but anna dominates maths, so i'm going to say a should be positive...

Oh is it convention? I just thought it had to be positive because my nazi teachers wouldn't give marks if there were fractions and it was not positive XD
