this is the "standard form" of a linear equation in x and y

the coefficients are capitalized because they are integers (no fractions)
___ also (by convention) A is positive

you can "find" it by converting from another linear form (like slope-intercept)

example ___ y = (2/3)x + 7
___ multiplying by 3 ___ 3y = 2x + 7
___ subtracting 3y ___ 0 = 2x - 3y + 7
