Linear Equations 2variables , Solutions Explanation

Linear equation in two variable

Every point on the graph of a linear equation in two variables does not represent a solution of the linear equation.

If a pair of linear equations in two variables is consistent, then the lines represented by two equations are

The graph of every linear equation in two variables need not be a line.

If a pair of linear equations in two variables is consistent, then the lines represented by two equations are (a) intersecting (b) parallel (c) always coincident (d) intersecting or coincident

The cost of a notebook is twice the cost of a pen. Write a linear equation in two variables to represent this statement.(Take the cost of a notebook to be Rs x and that of a pen to be Rs y).
