• Two linear equations in the same two variables are said to form a pair of linear equations in two variables. • The most general form of a pair of linear equations is a 1 x + b 1 y + c 1 = 0 a 2 x + b 2 y + c 2 = 0, where a 1, a 2, b 1, b 2, c 1,c 2 are real numbers, such that 2 2 22 ab a b11 22+ ≠ +≠0, 0. • A pair of linear equations is consistent if it has a solution – either a ax+by = r is called a linear equation in two variables. (The “two variables” are the x and the y.) The numbers a and b are called the coecients of the equation ax+by = r. The number r is called the constant of the equation ax+by = r. Examples. 10x 3y =5and2x 4y = 7 are linear equations in two variables. Solutions of equations A solution of a linear equation in two variables ax+by = r is a
