Learn about the plotting of graphs for a pair of linear equations in two variables, topic from CBSE Class 10 Mathematics.

The graph of a pair of linear equations in two variables is represented by two lines. (i) If the lines intersect at a point, then that point gives the unique solution of the two equations.

A linear equation is drawn as a straight line on a set of axes. To draw the graph we need coordinates. We generate these coordinates by substituting values into the linear equation.
