Answer:
To draw the graph of a linear equation in two variable a series of steps to be followed which is given below:Step I:Obtain the linear equation.Let the equation be ax +by + c = 0Step II: Express one unknown quantity in terms of other here. Express Y in terms of x to gety= - (ax+c/b)Step III:For any two values of x, calculate the corresponding values of y from the expression in step II to obtain two solutions say (x1, y1 and( x2 ,y2)Step IV:plot the points (x1, y1 and( x2 ,y2) on graph paper on a suitable scale.Step V:Draw a line passing through points marked in step IV. The line so obtained is the graph of the equation ax + by+c = 0 ---------------------------------------------------------------------------------------------------
