Question

as the definition says, a and b cannot be zero in the equation ax+bx+c=0,then why do we call 0.y+2x=5 as a linear equation in two variable. the value of B is zero​

Answer 1

Answer:

Any equation of the form ax+by+c=0 (i.e. a linear equation in one or two variables), will represent a straight line on the xy-plane, where both a and b should not be zero, i.e., at least one of a and b is non-zero.
