Question

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

• A. a = 0, c = 0
• B. a ≠ 0, b ≠ 0
• C. a ≠ 0, b = 0
• D. a = 0, b ≠ 0

Answer 1

The correct option is B a ≠ 0, b ≠ 0

A linear equation in two variables is of the form ax + by + c = 0, where a ≠ 0, b ≠ 0. If the values of “a” and “b” are equal to 0, the equation becomes c =0. Hence, the values of a and b should not be equal to 0.
