MCQ
A linear equation in two variables is of the form ax + by + c = 0, where:
- Aa = 0, c = 0
- Ba ≠ 0, b = 0
- Ca = 0, b ≠ 0
- Da ≠ 0, b ≠ 0

Answer
- a ≠ 0, b ≠ 0
Solution:
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.
