suppose the equation is x + y =10
then take y or x of your choice for eg. u took x is 5 then
x+y=10
5+y=10
y=10/5
y=2
so we have to consider one term and find the other...... and on graph the quadrants are ++ -+ -- +- so draw a scale and plot the point x is 5 its positive then it will be on x axis plot the point on 5 and y us 2 so it is also positive it eill on y axis so 5 and 2 plot the point and simply draw a line... and carry on by taking x as other no. u have to do 3 for the perfect ans....
it is linear equations in two variables so the second also do the same....
