Question

Which of the following condition(s) is/are necessary for ax + by + c = 0 to represent general form of a linear equation in two variables?

• A. a, b and c are real numbers.
• B. a, b and c are rational numbers.
• C. The values of both a and b are not zero.
• D. The value of c is not equal to zero.

Answer 1

Answer: (A), (C)

The correct options are
A a, b and c are real numbers.
C The values of both a and b are not zero.

The general form of a linear equation in two variables x, y is ax + by + c = 0
Where a, b and c are real numbers and a, b are not equal to zero.
