Summary :
(1) An equation of the form ax + by + c = 0 , where a, b and c are real numbers, such that a and b are not both zero, is called a linear equation in two variables.
(2) A linear equation in two variables has many solutions.
(3) The graph of every linear equation in two variables is a straight line.
(4) x = 0 is a equation of y axis and y = 0 is a equation of x axis.
(5) The graph of x = a is a straight line parallel to y- axis.
(6) The graph of y = a is a straight line parallel to x- axis.
(7) An equation of the type y = mx represents the a line passing through the origin.
