Pair of linear equations in two variables

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.

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

Draw the graph of each of the following linear equations in two variables: -x+y=6 (ii) y=2x

Given the linear equation 2x+3y-8=0 , write another linear equation in two variables such that the geometrical representation of the pair so formed is: (i) intersecting lines (ii) parallel lines (iii) coincident lines

Given the linear equation 2x+3y 8=0 , write another linear equation in two variables such that the geometrical representation of the pair so formed is:(i) intersecting lines (ii) parallel lines (iii) coincident lines
