The conditions for ax+by+c=0 to be a linear equation in two variables (x,y) are
a =0 and b = 0
+ ≠ 0
a can be zero but not b
b can be 0 but not a
Condition is that both a and b are not equal to 0. i.e a≠0 and b≠0
Assertion: For all values of k, -32,k is a solution of the linear equation 2x+3=0.
Reason: The linear equation ax+b=0 can be expressed as a linear equation in two variables as ax+y+b=0.
Now, choose the correct option.
