Question

if x is the no. of hours a labour is on work and y his wage in rupees then y=4x+3.draw the work wages graph of this equation. from the graph find the wages of a labour who put in four hours of work

Answer 1

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: Shown above

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

Answer 2

Answer:

Given linear equation in two variables is

y=4x + 3

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: Shown above

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