What is IS curve it's investment savings or income savings and if u can brief about it?

How is real income gonna increase if interest rate falls and in LM it’s opposite i fail to understand the concept kindly bried it up.

I wrote a series of articles on the IS and LM curves that may be of some help here, starting with: http://financialexamhelp123.com/islm-deriving-aggregate-demand-synopsis/

I highly recommend that article written by S2000magician. The CFA curriculum is _ totally confusing _. This outline really simplified the big picture for me.

Thank you so much it was a great help !!

Good to hear.
