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
