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* = 4*x* + 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* = 4*x* + 3 is:

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