5. Consider the translated square MS in EXAMPLE 7. Apply to this square the reflection matrix that reflects about the line at 45 degrees. Plot the translated square in black and the reflected square in red. Use axis([-1,5,-1,5]) and plot the line y z using the command plot([-1,5], [-1,5]); (this command plots the line connecting the points (-1,-1) and (5,5)). Add a legend and a grid. You should reproduce the figure below. Include the M-file and the figure
