If x is the number of hours a labourer is on work "and y is his wages in rupees then y=4x+3. Draw the work wages graph of this equation . From the graph , Find the wages of a labourer Who puts in 4 hours of work.

 Given linear equation in two variables is –

                                    y = 4x + 3  ............. (1)

where x is the number of hours a labourer is on work

and y is his wages in rupees.

From (1), When x = 0,we get  y = 3

              When x = 1, we get, y = 4 + 3 = 7

             When x = 2, we get, y = 8 + 3 = 11

The graph of y = 4x + 3 is:

From the graph, it can be seen that when number of work hours are 4, then wages of labour = Rs 19
