The amount of money earned from each paper is 0.5$.
Let us take two points on the line and find the slope this will give us how much he earns from each paper.
Taking two points [tex](2,1)[/tex] and [tex](4,2)[/tex]
Slope is given by
[tex]m=\dfrac{\Delta y}{\Delta x}\\\Rightarrow m=\dfrac{2-1}{4-2}\\\Rightarrow m=\dfrac{1}{2}\\\Rightarrow m=0.5[/tex]
So, the amount of money earned from each paper is 0.5$.
