We can take the two ordered pairs (2,3) and (4,4) to find the slope of the linear equation:
[tex]m=\frac{4-3}{4-2}=\frac{1}{2}[/tex]
then, we can use the point (4,4) to find the equation in slope intercept form:
[tex]\begin{gathered} y-4=\frac{1}{2}(x-4)=\frac{1}{2}x-\frac{4}{2}=\frac{1}{2}x-2 \\ \Rightarrow y=\frac{1}{2}x-2+4=\frac{1}{2}x+2 \\ y=\frac{1}{2}x+2 \\ \end{gathered}[/tex]
we have that the equation is y = 1/2 x +2. This means that for each order that comes to the warehouse, the number of orders that go out the warehouse will be half that number plus two.
