Things to remember in identifying linear equation in two variables.
It has two variables.
There is NO more than one variable in each term.
The exponent of the variable in each term is 1 (or the degree of the equation is 1)
There is NO variable in the denominator.
There is NO variable inside radical sign.
Generally, it is written in the form Ax + By=C.
