The equation: ax + by + c = 0 completely describes a linear equation in two variables where a, b, and c are real numbers.
False
The general form of a linear equation in 2 variables is: ax+by+c=0
where, x and y are variables
a, b, c are real numbers, and neither a nor b is equal to zero
Since, these conditions are missing in the question, and the variables are not clearly stated, the statement is incorrect.
