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.
WE HAVE Y=X..SO GIVING 2 VALUES TO X AND FINDING CORRESPONDING VALUES OF Y WE GET
X................0.....................10
Y................0.....................10
TAKE A SUITABLE SCALE PLOT THE 2 POINTS ABOVE ,JOIN THEM TO GET A STRAIGHT LINE GRAPH
THE GRAPH LOOKS LIKE THIS
SIMILARLY FOR THE OTHER PROBLEM......Y=-X........ WE GET
X................0.................10
Y................0.................-10
TAKE A SUITABLE SCALE PLOT THE 2 POINTS ABOVE ,JOIN THEM TO GET A STRAIGHT LINE GRAPH
THE GRAPH LOOKS LIKE THIS
