This code uses the matplotlib library to create a line plot. The x-axis values are generated using the numpy arange function, which creates an array of evenly spaced values from 0 to the length of Y_pred. The y-axis values are taken from the last column of the X_train dataset, which is accessed using the slicing notation [:, -1]. The plot is created using the '->' argument, which specifies that the plot should use a solid line with triangular markers pointing in the positive x-direction.
