Let's recall.
Linear equation in two variables
An equation which contains two variables and the degree of each term
containing variable is one is called a linear equation in two variables.
ar + by + c = 0 is the general forn of a linear equation in two variables:
a, b, c are real numbers and a, b are not equal to zero at the same time.
Ex 3r - 4y + 12 = 0 is the general form of equation 3x = 4y - 12
