Plot the model results via a call to sm$.$graphics.abline$\_$plot, passing in the results object computed above in the model$\_$results option, and assign the plot output to the variable fig

Extract the relevant plotting axes with the following expression: ax $=$ fig.axes$[0]$

Call the method ax$.$scatter with two arguments to plot Happiness versus LogGDP $($recall that LogGDP is now a particular column in the variable x that you have created: x$[\text{'}$LogGDP$\text{'}])$
