You can put this solution on YOUR website!
ANY LINEAR EQUATION IN X AND Y REPRESENTS A STRAIGHT LINE.TO DRAW A STRAIGHT LINE WE NEED ONLY 2 POINTS.BUT TO DRAW AN ACCURATE LINE WE BETTER SPACE THE POINTS SOME DISTANCE APART SAY 15 CM OR 6 INCHES APART.
\n" ); document.write( "WE HAVE Y=X..SO GIVING 2 VALUES TO X AND FINDING CORRESPONDING VALUES OF Y WE GET
\n" ); document.write( "X................0.....................10
\n" ); document.write( "Y................0.....................10
\n" ); document.write( "TAKE A SUITABLE SCALE PLOT THE 2 POINTS ABOVE ,JOIN THEM TO GET A STRAIGHT LINE GRAPH
\n" ); document.write( "THE GRAPH LOOKS LIKE THIS
\n" ); document.write( " $\"+graph%28+300%2C+300%2C+-10%2C+10%2Cx%29+\"$
\n" ); document.write( "SIMILARLY FOR THE OTHER PROBLEM......Y=-X........ WE GET
\n" ); document.write( "X................0.................10
\n" ); document.write( "Y................0.................-10
\n" ); document.write( "TAKE A SUITABLE SCALE PLOT THE 2 POINTS ABOVE ,JOIN THEM TO GET A STRAIGHT LINE GRAPH
\n" ); document.write( "THE GRAPH LOOKS LIKE THIS
\n" ); document.write( " $\"+graph%28+300%2C+300%2C+-10%2C+10%2C-x%29+\"$ \n" ); document.write( "

\n" );
