If x is the no.of hours a labourer is on work and y are his wages in rupees,then y=4x+3.Draw the work-wage graph.From the graph,find the wages of a labourer who puts in 4 hrs of work?

Follow the following steps.

1:On the coordinate axes , let x-axes denote the no. of hours ie work

and y axes the  wages.

 

 2:plot the graph  for the equation y =4x +3, by taking thye following points.(obtained by substituting random values of x and getting the corresponding values of y.

 (0,3),(1,7),(2,11)

3: This will a straight line and the required graph.

4:From x=4 , draw a perpendicular intersecting the graph  at a point say P.

5: The Y co-ordinate of the point is the required wages.

this should be 19.
