A linear equation in two variables has infinitely many solutions. 3. The graph of linear equation in two variables is always a straight line 1. If A is a square matrix, then if A is invertible every equation Ax = b has one and only one solution. Namely, x = A'b. 2. If A is not invertible, then Ax = b will have either no solution, or an infinite number of solutions. 3. If b = 0 then the set of all solution to Ax = 0 is called the nullspac the equation ax + by = c represents a straight line in the xy-plane and the equation has infinitely many solutions, the set of all points on the line.

A Linear equation is defined as an equation with the maximum degree of one only, for example, ax = b can be referred to as a linear equation, and when a Linear equation in two variable comes into the picture, it means that the entire equation has 2 variables present in it Linear Equations are a wide variety of equations altogether. There can be linear equations in one variable, linear equations in two variables, and so on. In every equation, one thing remains constant: The highest (and the only) degree of all variables in the equation should be 1. Other than that, constants (zero degree variables) can be there
