Here is something from my macroeconomics class. The U$.$S$.$ money supply $($the green dollars$)$ is totally controlled by the Federal Reserve Bank. They are the only ones who can legally print those green dollars. They obviously have $100$ percent control over the money supply. So how will we draw this money supply curve?

Multiple Choice

It will be drawn as totally vertical or straight up and down.

It will look like the regular upward sloping supply curve. All supply curves are drawn the same way.
