# Graphical illustration Excel

I have formulated a linear optimization model and solve it using the Excel Solver. How can I illustrate the slacks vs usage?

• Hello, and welcome to OR.SE. Your question is quite broad, and it will be difficult for us to provide a helpful answer. Please edit your question to indicate what, precisely, you are asking about. We can't (or won't) usually answer questions that just say "did I do this homework problem correctly?"

• I still don't really understand what you are asking. You know the usage (I assume you just mean the values of the decision variables) and you know the slacks, so can't you just plot them? Or do you mean something more specific when you say "graphically illustrate"? Mar 12, 2020 at 1:31

\begin{alignat}{5} \max \quad & z = & 3x_1 & + & 2 x_2 & & & &&\\ \mbox{s.t.} \quad & & x_1 & + & x_2 & \leq 9 && \tag{constraint 1}\\ & & 3x_1 & + & x_2 & \leq 18 && \tag{constraint 2}\\ & & x_1 &&& \leq 7 && \tag{constraint 3}\\ &&&& x_2 & \leq 6 && \tag{constraint 4}\\ && x_1 , x_2 \geq 0 \end{alignat}
