Vedclass · Answer

(A) linear equation in two variables is defined as an equation that can be written in the form $ax + by + c = 0$,where $a$,$b$,and $c$ are real numbers and $a$ and $b$ are not both zero.This means that at least one of the coefficients of the variables $x$ or $y$ must be non-zero.If $a = 0$ and $b = 0$,the equation becomes $c = 0$,which is not a linear equation in two variables.Therefore,the condition for a linear equation in two variables is $a^2 + b^2 
eq 0$,which implies that $a$ and $b$ cannot both be zero simultaneously.

$A$ linear equation in two variables is of the form $ax + by + c = 0$,where
