Question:
A linear equation in two variables x and y is of the form ax + by + c = 0, where
(a) a ≠ 0, b ≠ 0
(b) a ≠ 0, b = 0
(c) a = 0, b ≠ 0
(d) a = 0, c = 0
Solution:
(a) $a \neq 0, b \neq 0$
A linear equation in two variables $\mathrm{x}$ and $y$ is of the form $a x+b y+c=0$, where $a \neq 0$ and $b \neq 0$.
