The following graph plots the percentage change in the spot rate for a foreign currency along the horizontal axis, while measuring the interest rate differential (between a home countiy and a forelgn country) along the vertical axis. in refers to the interest rate in the home country, while if refers to the interest rate in a foregn country. On the following graph, use the blue line (circle symbol) to plot the combinations of percentage change of the foreign curnency spot rate and interest rate differential that are consistent with the international Fisher effect (IFE) theory
