Is 4x-y=1 a standard form equation

Standard form is ax+by=c where a, b, and c are integers and a is usually positive

some other people say that it is ax+by+c=0, but I like the first version better

so

4x-y=1

4x-1y=1

they are all integers, yes

so yes, it is in standard form

Does it have A, B, C? in the form if so than yes
