Refer to the list below:A formula of the form ax+by+c=0,ax+by+c=0 A linear equation in two variables is one in which a, b, ca, b, c are real numbers such that aa and bb are not zero.A linear equation with two variables has an infinite number of solutions.A straight line is the graph of a linear equation with two variables.The xx-axis and yy-axes equations are y=0y=0 and x=0x=0, respectively.Every point on the graph of a two-variable linear equation is a solution to the equation. In contrast, every solution of a linear equation in two variables represents a point on the equation’s graph.Topics and Sub-topicsThe best way to use the NCERT notes is first to address the problem yourself.
