Question

A form which is in ax+by+c=0 is a linear equation in two variables why we have given that both a and b are not equal to simultaneously zero if a or b will become zero then the equation will come in one variable ​

Answer 1

Step-by-step explanation:

If A and B can be Equal

It doesn't matter because if a and b are equal suppose a=b=1

Then the equation will be

x+y+c =0 which is also a linear equation in two variable
